`significant_drop_in_scrutinee`: Trigger lint also for scrutinees in `while let` and `if let`

This lint should also work for `if let` and `while let`, so this PR makes it actually work.

For `while let`, I can't think of any reason why this lint shouldn't be enabled. The only problem is that the lint suggests moving the significant drop above the `while let`, which is clearly invalid in the case of `while let`. I don't know if this is fixable, but this PR simply disables the wrong suggestions.

For `if let`, it seems that another lint called `if_let_mutex` has some overlapping functionality. But `significant_drop_in_scrutinee` is a bit stricter, as it will trigger even if the `else` branch does not try to lock the same mutex.

changelog: [`significant_drop_in_scrutinee`]: Trigger lint also for scrutinees in `while let` and `if let`.

changelog: new lint: [`cfg_not_test`]

I don't know whether to lint only the `attr` or also the item associated to it. I guess this would mean putting the check in another place than `check_attribute` but I can't find a way to get the associated item to the attribute.

Also, I'm not sure how to document this lint, I feel like my explications are bad.

[`unnecessary_to_owned`]: catch `to_owned` on byte slice to create temporary `&str`

Closes #11648

Detects the pattern `&String::from_utf8(bytes.to_vec()).unwrap()` and suggests `core::str::from_utf8(bytes).unwrap()`, which avoids the unnecessary intermediate allocation.

I decided to put this in the existing `unnecessary_to_owned` lint (rather than creating a new lint) for a few reasons:
- we get to use some of its logic (for example, recognizing any of the functions in the `to_owned` family, e.g. `to_vec`)
- the actual inefficient operation that can be avoided here is the call to `.to_vec()`, so this is in a way similar to the other cases caught by `unnecessary_to_owned`, just through a bunch of type conversions
- we can make this more "generic" later and catch other cases, so imo it's best not to tie this lint specifically to the `String` type

Add new lint `hashset_insert_after_contains`

This PR closes https://github.com/rust-lang/rust-clippy/issues/11103.

This is my first PR creating a new lint (and the second attempt of creating this PR, the first one I was not able to continue because of personal reasons). Thanks for the patience :)

The idea of the lint is to find insert in hashmanps inside if staments that are checking if the hashmap contains the same value that is being inserted. This is not necessary since you could simply call the insert and check for the bool returned if you still need the if statement.

rustdoc: update to pulldown-cmark 0.11

r? rustdoc

This pull request updates rustdoc to the latest version of pulldown-cmark. Along with adding new markdown extensions (which this PR doesn't enable), the new pulldown-cmark version also fixes a large number of bugs. Because all text files successfully parse as markdown, these bugfixes change the output, which can break people's existing docs.

A crater run, https://github.com/rust-lang/rust/pull/121659, has already been run for this change.

The first commit upgrades and fixes rustdoc. The second commit adds a lint for the footnote and block quote parser changes, which break the largest numbers of docs in the Crater run. The strikethrough change was mitigated in pulldown-cmark itself.

`needless_return`: Support `#[expect]` on the return statement

A fix for https://github.com/rust-lang/rust-clippy/issues/9361 suppresses `clippy::needless_return` if there are any attributes on the `return` statement. This leads to some unexpected behavior, as described in https://github.com/rust-lang/rust-clippy/issues/12998, where adding `#[expect(clippy::needless_return)]` suppresses the lint, but doesn't fulfill the expectation.

I now decided to manually fulfill any expectations, if they are before the attribute check.

b52ac9a89a Auto merge of #125507 - compiler-errors:type-length-limit, r=lcnr
Re-implement a type-size based limit

r? lcnr

This PR reintroduces the type length limit added in #37789, which was accidentally made practically useless by the caching changes to `Ty::walk` in #72412, which caused the `walk` function to no longer walk over identical elements.

Hitting this length limit is not fatal unless we are in codegen -- so it shouldn't affect passes like the mir inliner which creates potentially very large types (which we observed, for example, when the new trait solver compiles `itertools` in `--release` mode).

This also increases the type length limit from `1048576 == 2 ** 20` to `2 ** 24`, which covers all of the code that can be reached with craterbot-check. Individual crates can increase the length limit further if desired.

Perf regression is mild and I think we should accept it -- reinstating this limit is important for the new trait solver and to make sure we don't accidentally hit more type-size related regressions in the future.

Fixes https://github.com/rust-lang/rust-clippy/issues/11374

cc `@GuillaumeGomez`

Marking as draft: Does this lint even break public API? If I change a function signature from `fn foo(x: &mut T)` to `fn foo(x: &T)`, I can still call it with `foo(&mut x)`. The only "breaking" thing is that the `clippy::unnecessary_mut_passed` lint will complain that `&mut` at the callsite is not necessary, possibly trickling down to the crate user having to remote a `mut` from a variable. [Playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=058165a7663902e84af1d23e35c10d66).

Are there examples where this actually breaks public API, that I'm missing?

Tighten `fn_decl_span` for async blocks

Tightens the span of `async {}` blocks in diagnostics, and subsequently async closures and async fns, by actually setting the `fn_decl_span` correctly. This is kinda a follow-up on #125078, but it fixes the problem in a more general way.

I think the diagnostics are significantly improved, since we no longer have a bunch of overlapping spans. I'll point out one caveat where I think the diagnostic may get a bit more confusing, but where I don't think it matters.

6de87829da doc_lazy_continuation: blank comment line for gap
This change addresses cases where doc comments are separated
by blank lines, comments, or non-doc-comment attributes,
like this:

```rust
/// - first line
// not part of doc comment
/// second line
```

Before this commit, Clippy gave a pedantically-correct
warning about how you needed to indent the second line.
This is unlikely to be what the user intends, and has
been described as a "false positive" (since Clippy is
warning you about a highly unintuitive behavior that
Rustdoc actually has, we definitely want it to output
*something*, but the suggestion to indent was poor).

Let's `#[expect]` some lints: Stabilize `lint_reasons` (RFC 2383)

Let's give this another try! The [previous stabilization attempt](https://github.com/rust-lang/rust/pull/99063) was stalled by some unresolved questions. These have been discussed in a [lang team](https://github.com/rust-lang/lang-team/issues/191) meeting. The last open question, regarding the semantics of the `#[expect]` attribute was decided on in https://github.com/rust-lang/rust/issues/115980

I've just updated the [stabilization report](https://github.com/rust-lang/rust/issues/54503#issuecomment-1179563964) with the discussed questions and decisions. Luckily, the decision is inline with the current implementation.

This hopefully covers everything. Let's hope that the CI will be green like the spring.

01b3c24bf5 Rollup merge of #126893 - dtolnay:prec, r=compiler-errors
Eliminate the distinction between PREC_POSTFIX and PREC_PAREN precedence level

I have been tangling with precedence as part of porting some pretty-printer improvements from syn back to rustc (related to parenthesization of closures, returns, and breaks by the AST pretty-printer).

As far as I have been able to tell, there is no difference between the 2 different precedence levels that rustc identifies as `PREC_POSTFIX` (field access, square bracket index, question mark, method call) and `PREC_PAREN` (loops, if, paths, literals).

There are a bunch of places that look at either `prec < PREC_POSTFIX` or `prec >= PREC_POSTFIX`. But there is nothing that needs to distinguish PREC_POSTFIX and PREC_PAREN from one another.

d49994b060/compiler/rustc_ast/src/util/parser.rs (L236-L237)

d49994b060/compiler/rustc_hir_typeck/src/fn_ctxt/suggestions.rs (L2829)

d49994b060/compiler/rustc_hir_typeck/src/fn_ctxt/suggestions.rs (L1290)

In the interest of eliminating a distinction without a difference, this PR collapses these 2 levels down to 1.

There is exactly 1 case where an expression with PREC_POSTFIX precedence needs to be parenthesized in a location that an expression with PREC_PAREN would not, and that's when the receiver of ExprKind::MethodCall is ExprKind::Field. `x.f()` means a different thing than `(x.f)()`. But this does not justify having separate precedence levels because this special case in the grammar is not governed by precedence. Field access does not have "lower precedence than" method call syntax &mdash; you can tell because if it did, then `x.f[0].f()` wouldn't be able to have its unparenthesized field access in the receiver of a method call. Because this Field/MethodCall special case is not governed by precedence, it already requires special handling and is not affected by eliminating the PREC_POSTFIX precedence level.

Fixes #12444
Fixes #12460
Fixes #12749
Fixes #12757
Fixes #12929

I think the documentation for the function should describe what- and how this is fixing the issues well.
It avoids emitting a warning when the data being cloned borrows from the place to clone into, which is information that we can get from `PossibleBorrowerMap`. Unfortunately, it is a tiny bit tedious to match on the MIR like that and I'm not sure if this is possibly relying a bit too much on the exact MIR lowering for assignments.

Things left to do:
- [x] Handle place projections (or verify that they work as expected)
- [x] Handle non-`Drop` types

Let `qualify_min_const_fn` deal with drop terminators

Fixes #12677

The `method_accepts_droppable` check that was there seemed overly conservative.
> Returns true if any of the method parameters is a type that implements `Drop`.
> The method can't be made const then, because `drop` can't be const-evaluated.

Accepting parameters that implement `Drop` should still be fine as long as the parameter isn't actually dropped, as is the case in the linked issue where the droppable is moved into the return place. This more accurate analysis ("is there a `drop` terminator") is already done by `qualify_min_const_fn` [here](f5e250180c/clippy_utils/src/qualify_min_const_fn.rs (L298)), so I don't think this additional check is really necessary?

Fixing the other, second case in the linked issue was only slightly more involved, since `Vec::new()` is a function call that has the ability to panic, so there must be a `drop()` terminator for cleanup, however we should be able to freely ignore that. [Const checking ignores cleanup blocks](https://github.com/rust-lang/rust/blob/master/compiler/rustc_const_eval/src/transform/check_consts/check.rs#L382-L388), so we should, too?

The first commit renames `for_each_expr` to `for_each_expr_without_closures` and `for_each_expr_with_closures` to `for_each_expr`

needless_borrows_for_generic_args: Fix for &mut
This commit fixes a bug introduced in #12706, where the behavior of the
lint has been changed, to avoid suggestions that introduce a move. The
motivation in the commit message is quite poor (if the detection for
significant drops is not sufficient because it's not transitive, the
proper fix would be to make it transitive). However, #12454, the linked
issue, provides a good reason for the change — if the value being
borrowed is bound to a variable, then moving it will only introduce
friction into future refactorings.

Thus #12706 changes the logic so that the lint triggers if the value
being borrowed is Copy, or is the result of a function call, simplifying
the logic to the point where analysing "is this the only use of this
value" isn't necessary.

However, said PR also introduces an undocumented carveout, where
referents that themselves are mutable references are treated as Copy,
to catch some cases that we do want to lint against. However, that is
not sound — it's possible to consume a mutable reference by moving it.

To avoid emitting false suggestions, this PR reintroduces the
referent_used_exactly_once logic and runs that check for referents that
are themselves mutable references.

Thinking about the code shape of &mut x, where x: &mut T, raises the
point that while removing the &mut outright won't work, the extra
indirection is still undesirable, and perhaps instead we should suggest
reborrowing: &mut *x. That, however, is left as possible future work.

e8d02fe1cb Make top-level rustc_parse functions fallible.
Currently we have an awkward mix of fallible and infallible functions:
```
       new_parser_from_source_str
 maybe_new_parser_from_source_str
       new_parser_from_file
(maybe_new_parser_from_file)        // missing
      (new_parser_from_source_file) // missing
 maybe_new_parser_from_source_file
       source_str_to_stream
 maybe_source_file_to_stream
```
We could add the two missing functions, but instead this commit removes
of all the infallible ones and renames the fallible ones leaving us with
these which are all fallible:
```
new_parser_from_source_str
new_parser_from_file
new_parser_from_source_file
source_str_to_stream
source_file_to_stream
```
This requires making `unwrap_or_emit_fatal` public so callers of
formerly infallible functions can still work.

This does make some of the call sites slightly more verbose, but I think
it's worth it for the simpler API. Also, there are two `catch_unwind`
calls and one `catch_fatal_errors` call in this diff that become
removable thanks this change. (I will do that in a follow-up PR.)

Disables `indexing_slicing` for custom Index impls, specifically any implementations that also do not have a `get` method anywhere along the deref chain (so, for example, it still lints on Vec, which has its `get` method as part of the deref chain).

Thanks `@y21` for pointing me in the right direction with a couple of handy util functions for deref chain and inherent methods, saved a headache there!

febfa5157c Rollup merge of #125635 - fmease:mv-type-binding-assoc-item-constraint, r=compiler-errors
Rename HIR `TypeBinding` to `AssocItemConstraint` and related cleanup

Rename `hir::TypeBinding` and `ast::AssocConstraint` to `AssocItemConstraint` and update all items and locals using the old terminology.

Motivation: The terminology *type binding* is extremely outdated. "Type bindings" not only include constraints on associated *types* but also on associated *constants* (feature `associated_const_equality`) and on RPITITs of associated *functions* (feature `return_type_notation`). Hence the word *item* in the new name. Furthermore, the word *binding* commonly refers to a mapping from a binder/identifier to a "value" for some definition of "value". Its use in "type binding" made sense when equality constraints (e.g., `AssocTy = Ty`) were the only kind of associated item constraint. Nowadays however, we also have *associated type bounds* (e.g., `AssocTy: Bound`) for which the term *binding* doesn't make sense.

---

Old terminology (HIR, rustdoc):

```
`TypeBinding`: (associated) type binding
├── `Constraint`: associated type bound
└── `Equality`: (associated) equality constraint (?)
    ├── `Ty`: (associated) type binding
    └── `Const`: associated const equality (constraint)
```

Old terminology (AST, abbrev.):

```
`AssocConstraint`
├── `Bound`
└── `Equality`
    ├── `Ty`
    └── `Const`
```

New terminology (AST, HIR, rustdoc):

```
`AssocItemConstraint`: associated item constraint
├── `Bound`: associated type bound
└── `Equality`: associated item equality constraint OR associated item binding (for short)
    ├── `Ty`: associated type equality constraint OR associated type binding (for short)
    └── `Const`: associated const equality constraint OR associated const binding (for short)

Make `body_owned_by` return the `Body` instead of just the `BodyId`

fixes #125677

Almost all `body_owned_by` callers immediately called `body`, too, so just return `Body` directly.

This makes the inline-const query feeding more robust, as all calls to `body_owned_by` will now yield a body for inline consts, too.

I have not yet figured out a good way to make `tcx.hir().body()` return an inline-const body, but that can be done as a follow-up
