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,
    }
}
```
