3062: Implement slice pattern AST > HIR lowering r=jplatte a=jplatte
WIP. The necessary changes for parsing are implemented, but actual inference is not yet. Just wanted to upload what I've got so far so it doesn't get duplicated :)
Will fix#3043

3047: Update async unsafe fn ordering in parser r=matklad a=kiljacken
As of rust-lang/rust#61319 the correct order for functions that are both unsafe and async is: `async unsafe fn` and not `unsafe async fn`.
This commit updates the parser tests to reflect this, and corrects parsing behavior to accept the correct ordering.
Fixes#3025

3040: Rework value parameter parsing r=matklad a=tobz1000
Fixes#2847.
- `Fn__(...)` parameters with idents/patterns no longer parse
- Trait function parameters with arbitrary patterns parse
- Trait function parameters without idents/patterns no longer parse
- `fn(...)` parameters no longer parse with patterns other than a single ident
__Question__: The pre-existing test `param_list_opt_patterns` has been kept as-is, although the name no longer makes sense (it's testing `Fn__(...)` params, which aren't allowed patterns any more). What would be best to do about this?

2827: Fix array element attribute position r=matklad a=edwin0cheng
This PR fixed a bug which an ATTR node insert in the wrong place in array element. ~~And introduce `precede_next` for allow outer attributes to insert into a parsed `expr`.~~

2837: Accidentally quadratic r=matklad a=matklad
Our syntax highlighting is accdentally quadratic. Current state of the PR fixes it in a pretty crude way, looks like for the proper fix we need to redo how source-analyzer works.
**NB:** don't be scared by diff stats, that's mostly a test-data file

2641: Parse const generics r=matklad a=roblabla
Adds very primitive support for parsing const generics (`const IDENT: TY`) so that rust-analyzer stops complaining about the syntax being invalid.

2628: Add macro 2.0 support in parser r=matklad a=edwin0cheng
This PR added a new syntax kind : `MACRO_DEF` and a keyword `MACRO_KW`
there are two syntax for declarative macro 2.0 :
1. Normal : `macro m { ($i:ident) => {} }` , which handle similar to legacy one.
2. Call like: `macro m($i:ident) {}`, it produces a single token tree which have two child token trees : `($i:ident)` and `{}`

Although structs and unions have the same syntax and differ only in
the keyword, re-using the single syntax node for both of them leads to
confusion in practice, and propagates further down the hir in an
upleasent way.
Moreover, static and consts also share syntax, but we use different
nodes for them.
2343: implement assist invert_if r=matklad a=bravomikekilo
fix [issue 2219 invert if condition](https://github.com/rust-analyzer/rust-analyzer/issues/2219)
I put the assist cursor range to `if` of the if expression, because both condition and body will be replaced. Is there any way to replace them without cover the cursor position?
