This is a quick way to implement unresolved reference diagnostics.
For example, adding to VS Code config
"editor.tokenColorCustomizationsExperimental": {
"unresolvedReference": "#FF0000"
},
will highlight all unresolved refs in red.
4029: Fix various proc-macro bugs r=matklad a=edwin0cheng
This PRs does the following things:
1. Fixed#4001 by splitting `LIFETIME` lexer token to two mbe tokens. It is because rustc token stream expects `LIFETIME` as a combination of punct and ident, but RA `tt:TokenTree` treats it as a single `Ident` previously.
2. Fixed#4003, by skipping `proc-macro` for completion. It is because currently we don't have `AstNode` for `proc-macro`. We would need to redesign how to implement `HasSource` for `proc-macro`.
3. Fixed a bug how empty `TokenStream` merging in `proc-macro-srv` such that no L_DOLLAR and R_DOLLAR will be emitted accidentally.

3901: Add more heuristics for hiding obvious param hints r=matklad a=IceSentry
This will now hide `value`, `pat`, `rhs` and `other`. These words were selected from the std because they are used in commonly used functions with only a single param and are obvious by their use.
It will also hide the hint if the passed param **starts** or end with the param_name. Maybe we could also split on '_' and check if one of the string is the param_name.
I think it would be good to also hide `bytes` if the type is `[u8; n]` but I'm not sure how to get the param type signature.
Closes#3900

3826: Flatten nested highlight ranges during DFS traversal r=matklad a=ltentrup
Implements the flattening of nested highlights from #3447.
There is a caveat: I needed to add `Clone` to `HighlightedRange` to split highlight ranges ~and the nesting does not appear in the syntax highlighting test (it does appear in the accidental-quadratic test but there it is not checked against a ground-truth)~.
I have added a test case for the example mentioned in #3447.
