513a3615f6 Report invalid, nested, multi-segment crate-paths 
Specifically, things like:

use foo::{crate::bar};

Are now being caught, when before we only caught:

use foo::{crate};

74e3b48806 Parse correctly fn f<T>() where T: Fn() -> u8 + Send {} 
We used to parse it as T: Fn() -> (u8 + Send), which is different from
the rustc behavior of T: (Fn() -> u8) + Send

da8eb29a2f Macro patterns are not confused with expressions. 
We treat macro calls as expressions (there's appropriate Into impl),
which causes problem if there's expresison and non-expression macro in
the same node (like in the match arm).

We fix this problem by nesting macor patterns into another node (the
same way we nest path into PathExpr or PathPat). Ideally, we probably
should add a similar nesting for macro expressions, but that needs
some careful thinking about macros in blocks: `{ am_i_expression!() }`.

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

Allow attributes before function arguments 
This adds support for function calls of the form:

```rust
  (
    #[attr(...)] 1.2,
    #[attr_one(...)]
    #[attr_two(...)]
    1.5,
    ... etc ...
  )
```
