This allows us to handle more cases without a query cycle, which
includes certain cases that rustc accepted. That in turn means we avoid
triggering salsa-rs/salsa#257 on valid code (it will still happen if the
user writes an actual cycle).
We actually accept more definitions than rustc now; that's because rustc
only ignores bindings when looking up super traits, whereas we now also
ignore them when looking for predicates to disambiguate associated type
shorthand. We could introduce a separate query for super traits if
necessary, but for now I think this should be fine.
7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

8020: Power up goto_implementation r=matklad a=Veykril
by allowing it to be invoked on references of names, now showing all (trait)
implementations of the given type in all crates instead of just the defining
crate as well as including support for builtin types
Example screenshot of `impl`s of Box in `log`, `alloc`, `std` and the current crate. Before you had to invoke it on the definition where it would only show the `impls` in `alloc`.

8018: Make Ty wrap TyKind in an Arc r=flodiebold a=flodiebold
... to further move towards Chalk.
This is a bit of a slowdown (218ginstr vs 213ginstr for inference on RA), even though it allows us to unwrap the Substs in `TyKind::Ref` etc..

... like it will be in Chalk. We still keep `interned_mut` and
`into_inner` methods that will probably not exist with Chalk.
This worsens performance slightly (5ginstr inference on RA), but doesn't
include other simplifications we can do yet.
7574: Remove various redundant clones r=kjeremy a=yoshuawuyts
I noticed when running clippy through RA that there are a few instances where `clone` is called where it's not actually needed. I figured a small patch to remove these might be welcome here.
Thanks!

7570: Add doc gen to the `generate_enum_match_method` assist r=yoshuawuyts a=yoshuawuyts
Implements a small extension to https://github.com/rust-analyzer/rust-analyzer/pull/7562, generating default comments. I wasn't sure if this would fit the goals of Rust-Analyzer, so I chose to split it into a separate PR. This is especially useful when writing code in a codebase which uses `#![warn(missing_docs)]` lint, as many production-grade libraries do.
The comments we're generating here are similar to the ones found on [`Option::is_some`](https://doc.rust-lang.org/std/option/enum.Option.html#method.is_some) and [`Result::is_err`](https://doc.rust-lang.org/std/result/enum.Result.html#method.is_err). I briefly considered only generating these for `pub` types, but they seem small and unobtrusive enough that they're probably useful in the general case. Thanks!
## Example
__input__
```rust
pub(crate) enum Variant {
Undefined,
Minor, // cursor here
Major,
}
```
__output__
```rust
pub(crate) enum Variant {
Undefined,
Minor,
Major,
}
impl Variant {
/// Returns `true` if the variant is [`Minor`].
pub(crate) fn is_minor(&self) -> bool {
matches!(self, Self::Minor)
}
}
```
## Future Directions
This opens up the path to adding an assist for generating these comments on existing `is_` methods. This would make it both easy to document new code, and update existing code with documentation.
