Extend `trait_duplication_in_bounds` to cover trait objects

This PR extends `trait_duplication_in_bounds` to cover trait objects.

Currently,
```rs
fn foo(_a: &(dyn Any + Send + Send)) {}
```

generates no warnings. With this PR, it will complain about a duplicate trait and can remove it

check for `..` pattern in `redundant_pattern_matching`

The `redundant_pattern_matching` lint currently checks for `if let Some(_) = ...`, but not for `if let Some(..) = ...`.
This PR makes sure to also check for the `..` pattern in tuple structs.
It also found one such instance in clippy itself so that shows it's worth checking for this pattern as well 😅

Ignore `shadow` warns in code from macro expansions

This PR fixes https://github.com/rust-lang/rust-clippy/issues/9757

I am in doubt if just looking for `pat.span.from_expansion()` would be sufficient instead of looking for both `pat.span.desugaring_kind().is_some()` or `pat.span.from_expansion()`. The tests (including the new one) passes if I leave the only `if pat.span.from_expansion()`. Any feedbacks?

Also, this is my first PR here, sorry for anything and thanks for the patience!

Add size-parameter to unecessary_box_returns

Fixes #10641

This adds a configuration-knob to the `unecessary_box_returns`-lint which allows _not_ linting a `fn() -> Box<T>` if `T` is "large". The default byte size above which we no longer lint is 128 bytes (due to https://github.com/rust-lang/rust-clippy/issues/4652#issue-505670554, also used in #9373). The overall rational is given in #10641.

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list. They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Change the `extra_unused_type_parameters` lint to provide machine applicable suggestions rather than just help messages. Exception to this are cases when any unused type parameters appear bounded in where clauses - for now I've deemed these cases unfixable and separated them out. Future work might be able to provide suggestions in these cases.

Also, added a test case for the `avoid_breaking_exported_api` config option.

In uninit checking, add fallback for polymorphic types

After #10520, we always assumed that polymorphic types do not allow to be left uninitialized. But we can do better, by peeking into polymorphic types and adding a few special cases for going through tuples, arrays (because the length may be polymorphic) and blanket allowing all unions (like MaybeUninit).

491f63214a Auto merge of #104833 - Swatinem:async-identity-future, r=compiler-errors
Remove `identity_future` indirection

This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm.

Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]`annotation.

Fixes https://github.com/rust-lang/rust/issues/104826.

ff23e48c30 Auto merge of #108471 - clubby789:unbox-the-syntax, r=Nilstrieb,est31
Remove `box_syntax`

r? `@Nilstrieb`

This removes the feature `box_syntax`, which allows the use of `box <expr>` to create a Box, and finalises removing use of the feature from the compiler. `box_patterns` (allowing the use of `box <pat>` in a pattern) is unaffected.
It also removes `ast::ExprKind::Box` - the only way to create a 'box' expression now is with the rustc-internal `#[rustc_box]` attribute.
As a temporary measure to help users move away, `box <expr>` now parses the inner expression, and emits a `MachineApplicable` lint to replace it with `Box::new`

Closes #49733

e07c6b4899 Auto merge of #108872 - cjgillot:simp-const-prop, r=oli-obk
Strengthen state tracking in const-prop

Some/many of the changes are replicated between both the const-prop lint and the const-prop optimization.

Behaviour changes:
- const-prop opt does not give a span to propagated values. This was useless as that span's primary purpose is to diagnose evaluation failure in codegen.
- we remove the `OnlyPropagateInto` mode. It was only used for function arguments, which are better modeled by a write before entry.
- the tracking of assignments and discriminants make clearer that we do nothing in `NoPropagation` mode or on indirect places.

e65ad6f5d0 Auto merge of #10453 - Jarcho:test_utils, r=dswij
Add utility macros to help with writing tests.

Adds two utility macros to help with testing:
* `external` expands to it's argument tokens, but makes them appear to come from an external macro. Helps make tests for `in_external_macro` much more readable.
* `inline_macros` is an attribute macro which allows the use of a pseudo `inline!` macro which expands to it's argument tokens, but makes them appear to be from a crate-local macro expansion. This removes the need to write `macro_rules` boilerplate when testing how lints interact with macros.

---

`external`'s usage is simple. `external!(struct Foo { x: u32});` will make the struct appear as though it came from an external macro. Individual tokens can be escaped if needed. `external!($x + 0 / 10)` will make everything except `x` appear as though it came from an external macro. Can also use `$literal` and `$(tokens...)` as well.

---

`inline_macros` is more complicated due to compiler constraints. Given:
```rust
#[inline_macros]
fn foo() {
    inline!(5 + 5 / 10);
}
```
`inline!(5 + 5 / 10)` will be replace with a call to a generated macro which expands to the contained tokens.

Tokens can be escaped by prefixing them with `$`:
```rust
#[inline_macros]
fn foo() {
    let x = 5;
    inline!($x + 5 / $10);
}
```
This will pass `x` as an `ident` argument and `10` as a `literal` argument.

Token sequences can also be passed with `$(...)`:
```rust
#[inline_macros]
fn foo() {
    let mut x = 5;
    inline!(if $(x >= 5) {
        $x = 5;
    });
}
```
This will pass `x >= 5` as `tt` arguments, and `x` as an `ident` argument.

---

Not 100% sure `inline_macros` is actually worth having. It does make the tests a little easier to read once you're used to it and it becomes more useful once there are multiple macro tests. The verbosity of declaring single use macros starts to hurt at that point.

This rewords the message to focus on the error being an implicit ABI, rather than the `Rust` ABI. Also downgrades the suggestion to `MaybeIncorrect` and changes the suggestion span to better highlight the change.

Part 1 of #10233

The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`

The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params

Changes done to the functionality:

Allowing different error types for the functions was disallowed. So the following was linted before but is not after this change
```
impl Foo {
    pub len(&self) -> Result<usize, Error1> { todo!(); }
    pub is_empty(&self) -> Result<bool, Error2> { todo!(); }

Add `collection_is_never_read`

Fixes #9267

`@flip1995` and `@llogiq,` I talked with you about this one at Rust Nation in London last week. :-)

This is my first contribution to Clippy, so lots of feedback would be greatly appreciated.

- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

`dogfood` found one true positive (see #9509) and no false positives.

`lintcheck` found no (true or false) positives, even when running on an extended set of crates.
