d9ab4ff9a3 Remove blanket silencing of "type annotation needed" errors 
Remove blanket check for existence of other errors before emitting
"type annotation needed" errors, and add some eager checks to avoid
adding obligations when they refer to types that reference
`[type error]` in order to reduce unneded errors.

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,
    }
}
```
