8c00304bbb Make more traits of the From/Into family diagnostic items
Following traits are now diagnostic items:
- `From` (unchanged)
- `Into`
- `TryFrom`
- `TryInto`

This also adds symbols for those items:
- `into_trait`
- `try_from_trait`
- `try_into_trait`

e9b2cf4f64 Rollup merge of #81236 - estebank:everybody-loop-now, r=oli-obk
Gracefully handle loop labels missing leading `'` in different positions

Fix #81192.

* Account for labels when suggesting `loop` instead of `while true`
* Suggest `'a` when given `a` only when appropriate
* Add loop head span to hir
* Tweak error for invalid `break expr`
* Add more misspelled label tests
* Avoid emitting redundant "unused label" lint
* Parse loop labels missing a leading `'`

Each commit can be reviewed in isolation.

Fix formatting for removed lints

- Don't add backticks for the reason a lint was removed. This is almost
never a code block, and when it is the backticks should be in the reason
itself.
- Don't assume clippy is the only tool that needs to be checked for
backwards compatibility

I split this out of https://github.com/rust-lang/rust/pull/80527/ because it kept causing tests to fail, and it's a good change to have anyway.

Fix the reversed suggestion message of `stable_sort_primitive`.

Now Clippy emits `stable_sort_primitive` warning as follows:

```
warning: used sort instead of sort_unstable to sort primitive type `usize`
  --> src\asm.rs:41:13
   |
41 |             self.successors.sort();
   |             ^^^^^^^^^^^^^^^^^^^^^^ help: try: `self.successors.sort_unstable()`
   |
   = note: `#[warn(clippy::stable_sort_primitive)]` on by default
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#stable_sort_primitive
```

I think the position of `sort` and `sort_unstable` in the first line should be reversed.

2be935d396 Force token collection to run when parsing nonterminals
Fixes #81007

Previously, we would fail to collect tokens in the proper place when
only builtin attributes were present. As a result, we would end up with
attribute tokens in the collected `TokenStream`, leading to duplication
when we attempted to prepend the attributes from the AST node.

We now explicitly track when token collection must be performed due to
nomterminal parsing.

Fix path_to_res for enum inherent items

changelog: none

I tried to add `Option::is_some` to the paths but got a false positive from the invalid paths lint. Turns out the `path_to_res` function does not find inherent impls for enums. I fixed this and took the liberty to do some additional cleanup in the method.

size_of_in_element_count: Disable lint on division by byte-size

Fixes #6511

It is fairly common to divide some length in bytes by the byte-size of a single element before creating a `from_raw_parts` slice or similar operation. This lint would erroneously disallow such expressions.

Just in case, instead of simply disabling this lint in the RHS of a division, keep track of the inversion and enable it again on recursive division.

391bb218b5 size_of_in_element_count: Separate test file in expressions and functions
An upcoming test case for new expresssion variants make the stderr file
go over 200 lines. Split this test case in two to have a clear
distinction between checking whether the lint is still applying on
all the functions with member counts as argument, versus validating
various member-count expressions that may or may not be invalid.

New Lint: inspect_then_for_each

**Work In Progress**

This PR addresses [Issue 5209](https://github.com/rust-lang/rust-clippy/issues/5209) and adds a new lint called `inspect_then_for_each`.

Current seek some guidance.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- \[x] 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`

e21270ba0e Auto merge of #6608 - rail-rain:note_on_as_conversions, r=phansch
Add a note to `as_conversions`

I have seen a couple of examples where there are some misunderstandings of `as_conversions` ([1](https://github.com/rust-lang/rust-clippy/issues/5890#issuecomment-671852546), [2](https://github.com/rust-lang/rust-clippy/issues/6116#issuecomment-704251710) and [3](https://github.com/rust-lang/rust-clippy/issues/6428)). This PR adds the note that explains its purpose and relationship with other `as` related casts. Open question: should I list every related lints for discoverbility, or just suggest how to find these? I chose the former because there's no way to list only and all `as` related lints (e.g. on All the Clippt Lints, 'cast' includes some noises, but `cast_` excludes some) even though I cannot guarantee the list will be updated to include future changes.
