7907: Autoderef with visibility r=cynecx a=cynecx
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841.
I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below

By including the crate itself, we make the resulting set closed with
respect to `transitve_reveres_dependencies` operation, as it becomes a
proper transitive closure. This just feels more proper and mathy.
And, indeed, this actually allows us to simplify call sites somewhat.
This in particular means storing a chalk_ir::Environment, not our
TraitEnvironment. This makes InEnvironment not usable for Type, where we
need to keep the full TraitEnvironment.
8133: Ignore type bindings in generic_predicates_for_param (fix panic on ena and crates depending on it) r=flodiebold a=flodiebold
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..

What happens here is that we lower `: ` to a missing expression, and
then correctly record that the corresponding field expression resolves
to a specific field. Where we fail is in the mapping of syntax to this
missing expression. Doing it via `ast_field.expr()` fails, as that
expression is `None`. Instead, we go in the opposite direcition and ask
each lowered field about its source.
This works, but has wrong complexity `O(N)` and, really, the
implementation is just too complex. We need some better management of
data here.
use vec![] instead of Vec::new() + push()
avoid redundant clones
use chars instead of &str for single char patterns in ends_with() and starts_with()
allocate some Vecs with capacity to avoid unneccessary resizing
7873: Consider unresolved qualifiers during flyimport r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7679
Takes unresolved qualifiers into account, providing better completions (or none, if the path is resolved or do not match).
Does not handle cases when both path qualifier and some trait has to be imported: there are many extra issues with those (such as overlapping imports, for instance) that will require large diffs to address.
Also does not do a fuzzy search on qualifier, that requires some adjustments in `import_map` for better queries and changes to the default replace range which also seems relatively big to include here.

7813: Inline TypeCtor into Ty r=flodiebold a=Veykril
This removes the `ApplicationTy` variant from `Ty` bringing the representation a lot closer to chalk's `TyKind`.

7804: Introduce TypeCtor::Scalar r=lnicola a=Veykril
`TypeCtor::Int(..) | TypeCtor::Float(..) | TypeCtor::Char | TypeCtor::Bool` => `TypeCtor::Scalar(..)`, in this case we can actually just straight up use `chalk_ir::Scalar` already since its just a POD without any IDs or anything.
