5637: SSR: Matching trait associated constants, types and functions r=matklad a=davidlattimore
This fixes matching of things like `HashMap::default()` by resolving `HashMap` instead of `default` (which resolves to `Default::default`).
Same for associated constants and types that are part of a trait implementation.
However, we still don't support matching calls to trait methods.

5553: Add fix ranges for diagnostics r=matklad a=SomeoneToIgnore
A follow-up of https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Less.20red.20in.20the.20code
Now diagnostics can apply fixes in a range that's different from the range used to highlight the diagnostics.
Previous logic did not consider the fix range, having both ranges equal, which could cause a lot of red noise in the editor.
Now, the fix range gets used with the fix, the diagnostics range is used for everything else which allows to improve the error highlighting.
before:

`MissingFields` and `MissingPatFields` diagnostics now have the fix range as `ast::RecordFieldList` of the expression with an error (as it was before this PR), and the diagnostics range as a `ast::Path` of the expression, if it's present (do you have any example of `ast::Expr::RecordLit` that has no path btw?).
The rest of the diagnostics have both ranges equal, same as it was before this PR.

4743: Add tracking of packed repr, use it to highlight unsafe refs r=matklad a=Nashenas88
Taking a reference to a misaligned field on a packed struct is an
unsafe operation. Highlight that behavior. Currently, the misaligned
part isn't tracked, so this highlight is a bit too aggressive.
Fixes #4600

5692: Add support for extern crate r=jonas-schievink a=Nashenas88

There doesn't seem to be any need for it, and removing it simplies
several paths of code that depend on it.

5684: Semantic highlighting for unsafe union field access r=jonas-schievink a=Nashenas88
This change adds support for unions in inference and lowering, then extends on that to add the unsafe semantic modifier on field access only. The `is_possibly_unsafe` function in `syntax_highlighting.rs` could be extended to support fns and static muts so that their definitions are not highlighted as unsafe, but only their usage.
Also, each commit of this PR updates the tests. By reviewing the files by commit, it's easy to see how the changes in the code affected the tests.
