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.

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() => {},
_ => {},
}
}
```
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`.
Extend `unnecessary_to_owned` to handle `Borrow` trait in map types
Fixes https://github.com/rust-lang/rust-clippy/issues/8088.
Alternative to #12315.

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
Always evaluate free constants and statics, even if previous errors occurred
work towards https://github.com/rust-lang/rust/issues/79738
We will need to evaluate static items before the `definitions.freeze()` below, as we will start creating new `DefId`s (for nested allocations) within the `eval_static_initializer` query.
But even without that motivation, this is a good change. Hard errors should always be reported and not silenced if other errors happened earlier.
Default test output conflict handling to error
https://github.com/oli-obk/ui_test/pull/175 got rid of the `bool` that controlled the default handling so we need to specify it ourselves

Remove `$DIR` replacement
This won't cause problems because the old `$DIR` replacement was based on the parent of the test path, which for us is relative: 5471e0645a/tests/compile-test.rs (L122)
The new pattern being `"tests/{test_dir}"` is more clearly relative
That's why we have custom filters applied to the toml/cargo tests where absolute paths do appear in the output 5471e0645a/tests/compile-test.rs (L198-L202)
Removing it allows clicking the paths in the terminal

Ensure ASM syntax detect `global_asm!` and `asm!` only on x86 architectures
The ASM syntax lint is only relevant on x86 architectures, so this PR ensures it doesn't trigger on other architectures. This PR also makes the lints check `global_asm!` items as well as `asm!` expressions.
changelog: Check `global_asm!` items in the ASM syntax lints, and fix false positives on non-x86 architectures.
When encountering a verbose/multipart suggestion that has changes
that are only caused by different capitalization of ASCII letters that have
little differenciation, expand the message to highlight that fact (like we
already do for inline suggestions).
The logic to do this was already present, but implemented incorrectly.
Ignore imported items in `min_ident_chars`
Suppress the `min_ident_chars` warning for items whose name we cannot control. Do not warn for `use a::b`, but warn for `use a::b as c`, since `c` is a local identifier.
Fixes#12232

[`implied_bounds_in_impls`]: avoid linting on overlapping associated tys
Fixes#11880
Before this change, we were simply ignoring associated types (except for suggestion purposes), because of an incorrect assumption (see the comment that I also removed).
For something like
```rs
trait X { type T; }
trait Y: X { type T; }
// Can't constrain `X::T` through `Y`
fn f() -> impl X<T = i32> + Y<T = u32> { ... }
```
We now avoid linting if the implied bound (`X<T = i32>`) "names" associated types that also exists in the implying trait (`trait Y`). Here that would be the case.
But if we only wrote `impl X + Y<T = u32>` then that's ok because `X::T` was never constrained in the first place.
I haven't really thought about how this interacts with GATs, but I think it's fine. Fine as in, it might create false negatives, but hopefully no false positives.
(The diff is slightly annoying because of formatting things. Really the only thing that changed in the if chain is extracting the `implied_by_def_id` which is needed for getting associated types from the trait, and of course actually checking for overlap)
cc `@Jarcho` ? idk if you want to review this or not. I assume you looked into this code a bit to find this bug.
