78d6b88f21 Add more tests, refactor array lengths/consteval work 
Fix #2922: add unknown length as a condition for a type having unknown.

Incorporate reviews:

* Extract some of the const evaluation workings into functions
* Add fixmes on the hacks
* Add tests for impls on specific array lengths (these work!!! 😁)
* Add tests for const generics (indeed we don't support it yet)

Now we will get the type of `[0u8; 4]`.

Merge #8799 
8799: Add basic support for array lengths in types r=flodiebold a=lf-

This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead
of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range
array declarations are unsupported as before.

I don't know why a bunch of our rustc tests had single quotes inside
strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's
bad? Maybe something in a nightly?

8539:  fix: Do not propose inherent traits in flyimports and import assists r=flodiebold a=SomeoneToIgnore

Closes https://github.com/rust-analyzer/rust-analyzer/issues/8520

I've went with a separate method approach, since the [highlighted code](https://github.com/rust-analyzer/rust-analyzer/issues/8520#issuecomment-819856337) has not`Type` and uses `Ty` to get his data, but the code I had to change has no access to `Ty` and has `Type` only.

8432: decl_check: consider outer scopes' allows r=jonas-schievink a=lf-

Fix #8417. Also makes it less noisy about no_mangle annotated stuff the
user can do nothing about.

Note: this still is broken with bitfield! macros. A repro in an ignore
test is included here. I believe this bug is elsewhere, and I don't
think I can work around it here.

I would like help filing the remaining bug, as it does actually affect
users, but I don't know how to describe the behaviour (or even if it
is unintended).

272a8dce4f Fix crash on syn involving lifetimes returned by Chalk 
If we get lifetime variables back in autoderef, just immediately replace
them by static lifetimes for now. Method resolution doesn't really deal
correctly with new variables being introduced (this needs to be fixed
more properly).

This fixes `rust-analyzer analysis-stats --with-deps` crashing in the RA
repo.
