1105: [WIP] Implement ra_mbe meta variables support r=matklad a=edwin0cheng
This PR implements the following meta variable support in `ra_mba` crate (issue #720):
- [x] `path`
- [ ] `expr`
- [ ] `ty`
- [ ] `pat`
- [ ] `stmt`
- [ ] `block`
- [ ] `meta`
- [ ] `item`
*Implementation Details*
In the macro expanding lhs phase, if we see a meta variable type, we try to create a `tt:TokenTree` from the remaining input. And then we use a special set of `ra_parser` to parse it to `SyntaxNode`.

1103: Array inference r=flodiebold a=Lapz
Fixes the final item in #394. The only problem is that infering the repeat cause some types to be infered twices.
i.e
```rust
fn test() {
let y = unknown;
[y, &y];
}
```
results in the following diff:
```diff
[11; 48) '{ ...&y]; }': ()
[21; 22) 'y': &{unknown}
[25; 32) 'unknown': &{unknown}
-[38; 45) '[y, &y]': [&&{unknown}]
+[38; 45) '[y, &y]': [&&{unknown};usize]
[39; 40) 'y': &{unknown}
+[39; 40) 'y': &{unknown}
[42; 44) '&y': &&{unknown}
[43; 44) 'y': &{unknown}
```
Should the code produce two inference results for 'y' and if not could any tell me what needs to change.

1117: [WIP] Tuple struct index inference r=matklad a=robojumper
The first commit adds a helper struct `ast::FieldKind` to facilitate inference.
The second commit adds a slightly modified test from #1109 while mentioning that there is a problem with how we're handling tuple indexing / floats.

1101: Parse unsafe async / const unsafe fns properly r=matklad a=robojumper
Also adds tests that `unsafe async fn` as well as `const unsafe fn` parse properly and that these keywords in the reversed order cause parse errors.
[Playground link to verify that this is the correct order.](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=7850b8d92579de31c38f835f76afa4ce)
Closes#1086.
