864: Fix handling of generics in tuple variants and refactor a bit r=matklad a=flodiebold
(The problem was that we created separate substitutions for the return value, so we lost the connection between the type arguments in the constructor call and the type arguments of the result.)
Also make them display a tiny bit nicer.
Fixes#860.

876: Fix join_lines not adding a comma after join_single_expr_block with match arm r=matklad a=vipentti
Fixes#868

We will also remove optional whitespace between the expression and the comma.
e.g.
```rust
fn foo() {
let x = (<|>{
4
} ,); // NOTE: whitespace
}
```
becomes
```rust
fn foo() {
let x = (<|>4,);
}
```
867: This moves the parser to separate crate r=matklad a=matklad
That makes parser independent form both the token and the tree representation.

This is done in `infer_path_expr`. When `Resolver::resolve_path` returns
`PartiallyResolved`, we use the returned `Resolution` together with the given
`segment_index` to check if we can find something matching the segment at
segment_index in the impls for that particular type.
863: Token source r=matklad a=matklad
Some reshuffling of parser's API with the eye towards extracting parse **without** syntax tree into a separate crate, to be used with macro expansion

Benchmarks show no difference. This is probably because we are
bottlenecked on memory allocations, and we should fix that, but we are
not optimizing for performance just yet.
