Merge #4227 
4227: Report invalid, nested, multi-segment crate-paths r=matklad a=djrenren

There was a bug in the previous path-validating code that didn't detect multi-segment paths that started with `crate`.

```rust
// Successfully reported
use foo::{crate};

// BUG: was not being reported
use foo::{crate::bar};
```

This was due to my confusion about path-associativity. That is, the path with no qualifier is the innermost path, not the outermost. I've updated the code with a lot of comments to explain what's going on. 

This bug was discovered when I found an erroneous `ok` test which I reported here: 
https://github.com/rust-analyzer/rust-analyzer/issues/4226

This test now fails and has been modified, hopefully in the spirit of the original test, to be correct.  Sorry about submitting the bug in the first place!

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 {}

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!() }`.
