Look for `implied_bounds_in_impls` in more positions
With this, we lint `impl Trait` implied bounds in more positions:
- Type alias impl trait
- Associated type position impl trait
- Argument position impl trait
- these are not opaque types, but instead are desugared to `where` clauses, so we need extra logic for finding them (`check_generics`), however the rest of the logic is the same
Before this, we'd only lint RPIT `impl Trait`s.
"Hide whitespaces" and reviewing commits individually might make this easier
changelog: [`implied_bounds_in_impls`]: start linting implied bounds in APIT, ATPIT, TAIT
Merge `single_call_fn` post-crate visitor into lint pass
The `single_call_fn` lint worked by first collecting a list of function definitions in the lint pass, then populating the list of uses for each function in a second visitor after the crate is checked.
Doing another pass through the crate shouldn't be needed, and we should be able to do it in the same lint pass, by looking for path references to functions only and then processing them post-crate.
Other changes:
- `FxHashMap` -> `FxIndexMap` so that we emit warnings in a consistent order, as we see them (making the diff a bit confusing to look at, because warnings were moved around)
- no longer storing a `Vec<Span>` per function: an enum representing "seen once" or "seen more than once" should be enough (only the first element is used later)
- "used here" help is now a note
I also noticed that it lints on trait methods with a default implementation, but not on regular trait methods without a body (because that's what `check_fn` does). I'm not sure if that's useful though, maybe we shouldn't lint trait methods at all? It's not like you can avoid it sometimes (but then again it's a restriction lint). Either way, I left the behavior where it was before so that there are no functional changes made in this PR and it's purely a refactor. I can change it though

FIX(12243): redundant_guards
Fixed#12243
changelog: Fix[`redundant_guards`]
I have made a correction so that no warning does appear when y.is_empty() is used within a constant function as follows.
```rust
pub const fn const_fn(x: &str) {
match x {
// Shouldn't lint.
y if y.is_empty() => {},
_ => {},
}
}
```
Add new `unnecessary_get_then_check` lint
No issue linked to this as far as I can see. It's a lint I discovered that could be added when I worked on another lint.

Pause PR assignments for xFrednet :)
My life is currently a bit chaotic, and it feels like I can't give reviews the attention they need. I'll finish the PRs I'm assigned to, write the changelogs, and am available when I get pinged etc.
This is only intended as a temporary pause, as I still genuinely enjoy working with everyone in this repo and seeing Clippy grow day by day.

A warning is now suppressed when "<str_va> if <str_var>.is_empty" is used in a constant function.
FIX: instead of clippy_util::in_const
FIX: Merged `redundant_guards_const_fn.rs` into `redundant_guards.rs`.
Take lifetime extension into account in `ref_as_ptr`
fixes#12255
This should be merged upstream as well. Changing `let x = &temp as *const _` into `let x = from_ref(&temp)` is UB.

Allow unused_imports, and unused_import_braces on `use`
Fixes https://github.com/rust-lang/rust-clippy/issues/12223.
Both `unused_import_braces` and `unused_imports` are valid on `use`-items, additional to the two previously allowed.

Coming back to reviewer rotation
After this current CPP period, in which I set myself as on-vacation to focus on performance, I'm now available again. I'd love if my vacation status wasn't present in version control

Fix: no_effect_underscore_binding fires on ignored parameters of async fns
Fixes#12279
changelog: Fix [`no_effect_underscore_binding`])
The warning is no longer displayed when an underscore is given in the parameter name of an asynchronous function.
----
UPDATE: add async block into test.
FIX: no_effect
Fixed asynchronous function parameter names with underscores so that warnings are not displayed when underscores are added to parameter names
ADD: test case
