fix: prefix prelude items whose name collides in current scope
Fixes#13873
When we assemble path for prelude items whose name collides with other item in scope, we should always prefix it with module paths.
fix: merge multiple intersecting ranges
Fixes#13791
In `check_intersection_and_push()`, there may exist two ranges we should merge with the new one. We've been assuming there should be only one range that intersects, which lead to [this assertion](da15d92a32/crates/text-edit/src/lib.rs (L192)) to fail under specific circumstances.
Use `rustc_safe_intrinsic` attribute to check for intrinsic safety
Instead of maintaining a list that is poorly kept in sync we can just use the attribute.
This will make new RA versions unusable with old toolchains that don't have the attribute yet. Should we keep maintaining the list as a fallback or just don't care?
derive 'Hash'
clippy doesn't like that `PartialEq` is derived, and `Hash` is manually implemented. This PR resolves that by deriving the `Hash` implementation.
Moar linting: needless_borrow, let_unit_value, ...
* There are a few needless borrows that don't seem to be needed. I even did a quick assembly comparison and posted a q to stackoveflow on it. See [here](https://stackoverflow.com/questions/74910196/advantages-of-pass-by-ref-val-with-impl-intoiteratoritem-impl-asrefstr)
* removed several `let _ = ...` when they don't look necessary (even a few ones that were not suggested by clippy (?))
* some unneeded assignment+return - keep the code a bit leaner
* a few `writeln!` instead of `write!`, or even consolidate write!
* a nice optimization to use `ch.is_ascii_digit` instead of `ch.is_digit(10)`
fix: handle lifetime variables in `CallableSig` query
Fixes#13838
The problem is similar to #13223: we've been skipping non-empty binders, letting lifetime bound variables escape.
I ended up refactoring `hir_ty::callable_sig_from_fnonce()`. Like #13223, I chose to make use of `InferenceTable` which is capable of handling variables (I feel we should always use it when we solve trait-related stuff instead of manually building obligations/queries).
I couldn't make up a test that crashes without this patch (since the function I'm fixing is only used *outside* `hir-ty`, simple `hir-ty` test wouldn't cause crash), but at least I tested with my local build and made sure it doesn't crash with the code in the original issue. I'd appreciate any help to find a regression test.

Inline all format arguments where possible
This makes code more readale and concise,
moving all format arguments like `format!("{}", foo)` into the more compact `format!("{foo}")` form.
The change was automatically created with, so there are far less change of an accidental typo.
```
cargo clippy --fix -- -A clippy::all -W clippy::uninlined_format_args

Clippy-fix explicit auto-deref
Seems like these can be safely fixed. With one, I was particularly surprised -- `Some(pats) => &**pats,` in body.rs?
```
cargo clippy --fix -- -A clippy::all -D clippy::explicit_auto_deref
```
