d7270712cb Auto merge of #63180 - varkor:trait-alias-impl-trait, r=Centril 
Change opaque type syntax from `existential type` to type alias `impl Trait`

This implements a new feature gate `type_alias_impl_trait` (this is slightly different from the originally proposed feature name, but matches what has been used in discussion since), deprecating the old `existential_types` feature.

The syntax for opaque types has been changed. In addition, the "existential" terminology has been replaced with "opaque", as per previous discussion and the RFC.

This makes partial progress towards implementing https://github.com/rust-lang/rust/issues/63063.

```
error: unexpected closing `)`

   |
LL |     for ( elem in vec ) {
   |         --------------^

   |         opening `(`
   |         help: remove parenthesis in `for` loop: `elem in vec`
```

Rollup merge of #62668 - goodmanjonathan:fix-62660, r=estebank 
Fix #62660

If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.
