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.
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.
Remove hir::Expr::MacroStmts
This hir expression isn't needed and only existed as it was simpler to
deal with at first as it gave us a direct mapping for the ast version of
the same construct. This PR removes it, properly handling the statements
that are introduced by macro call expressions.

feature: Assist to turn match into matches! invocation
Resolves#12510
This PR adds an assist, which convert 2-arm match that evaluates to a boolean into the equivalent matches! invocation.
