5748825cc8 Auto merge of #61682 - Centril:stabilize-type_alias_enum_variants, r=petrochenkov 
Stabilize `type_alias_enum_variants` in Rust 1.37.0

Stabilize `#![feature(type_alias_enum_variants)]` which allows type-relative resolution with highest priority to `enum` variants in both expression and pattern contexts. For example, you may now write:

```rust
enum Option<T> {
    None,
    Some(T),
}

type OptAlias<T> = Option<T>;

fn work_on_alias(x: Option<u8>) -> u8 {
    match x {
        OptAlias::Some(y) => y + 1,
        OptAlias::None => 0,
    }
}
```

e6ee8a0d44 rustc: produce AST instead of HIR from hir::lowering::Resolver methods. 2019-06-25 15:34:57 +03:00

3cc3486733 Auto merge of #62075 - Centril:guardless-match-arms, r=petrochenkov 
Remove `ast::Guard`

With the introduction of `ast::ExprKind::Let` in https://github.com/rust-lang/rust/pull/60861, the `ast::Guard` structure is now redundant in terms of representing [`if let` guards](https://github.com/rust-lang/rust/issues/51114) in AST since it can be represented by `ExprKind::Let` syntactically. Therefore, we remove `ast::Guard` here.

However, we keep `hir::Guard` because the semantic representation is a different matter and this story is more unclear right now (might involve `goto 'arm` in HIR or something...).

Remove some unnecessary symbol interner ops

* Don't gensym symbols that don't need to worry about colliding with other symbols
* Use symbol constants instead of interning string literals in a few places.

46b9ed4fa1 Rename "Associated*" to "Assoc*" 
We are going to uniform the terminology of all associated items.
Methods that may or may not have `self` are called "associated
functions". Because `AssociatedFn` is a bit long, we rename `Associated`
to `Assoc`.
