212f0477f2 Make diverging type variables work again
Chalk doesn't know about the `diverging` flag, so we need to instead
propagate it before fully resolving the variables.

Merge #8813
8813: Get some more array lengths! r=lf- a=lf-

This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of:

* `let a: [u8; 2] = ...`
* `let a = b"aaa"`
* `let a = [0u8; 4]`

I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!).

Fixes #2922.

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)

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?

c2aefd5b95 Don't look in super traits for <T as Trait>::Assoc
This isn't actually how it works, you have to specify the exact trait
that has the associated type.

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.
