fix: sort all bounds on trait object types
Fixes#13181#12793 allowed different ordering of trait bounds in trait object types but failed to account for the ordering of projection bounds. I opted for sorting all the bounds at once rather than splitting them into `SmallVec`s so it's easier to do the same thing for other bounds when we have them.
fix: Insert whitespaces into static & const bodies if they are expanded from macro on hover
Partially fixes#13143.
To resolve the other part we need to expand macros in unevaluated static & const bodies, and I'm not sure we want to. If for example it includes a call to `assert!()`, expanding it will lead to worse hover.
fix: correct broken logic for return complition
It seems that we've accidentally deleted the tests here couple of years
ago, and then fairly recently made a typo during refactor as well.
Reinstall tests, with coverage marks this time :-)

Lift out the module scope into a field in the Resolver
A Resolver *always* has a module scope at the end of its scope stack,
instead of encoding this as an invariant we can just lift this scope
out into a field, allowing us to skip going through the scope vec
indirection entirely.

feat: Implement `feature(exhaustive_patterns)` from unstable Rust
Closes#12753
Recognize Rust's unstable `#![feature(exhaustive_patterns)]` (RFC 1872). Allow omitting visibly uninhabited variants from `match` expressions when the feature is on.
This adjusts match checking to the current implementation of the postponed RFC 1872 in rustc.
fix: Parse TypePathFn with preceding `::`
e.g. `impl Fn::() -> ()`.
Fixes#13157. This was the problem, not that the path was not at the end.
I could unify the parsing of `::` of TypePathFn with that of generic arg list, but some code relies on the `::` of generic arg list to be inside it.
fix: Lower float literals with underscores
Fixes#13155 (the problem was the `PI` is defined with `_f64` suffix). `PI` is still truncated, though, because `f64` cannot represent the value with full precision.
Properly handle break resolution inside non-breakable expressions
We now diagnose invalid `continue` expressions and properly handle things like `async` blocks which prevent labels from resolving further. Cleaned this up since `label_break_value` is on the way to stabilization in rust (🎉 finally) and we weren't handling breaks for blocks properly yet.
proc_macro/bridge: send diagnostics over the bridge as a struct
This removes some RPC when creating and emitting diagnostics, and
simplifies the bridge slightly.
After this change, there are no remaining methods which take advantage
of the support for `&mut` references to objects in the store as
arguments, meaning that support for them could technically be removed if
we wanted. The only remaining uses of immutable references into the
store are `TokenStream` and `SourceFile`.

Highlight namerefs by syntax until proc-macros have been loaded
Usually when loading up a project, once loading is done we start answering highlight requests while proc-macros haven't always been loaded yet, so we start out with showing a lot of unresolved name-refs. After this PR, we'll use syntax based highlighting for those unresolved namerefs until the proc-macros have been loaded.
