6cb28b6617 Ident::with_empty_ctxt -> Ident::with_dummy_span 
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.

67d6ce4206 syntax_pos: NO_EXPANSION/SyntaxContext::empty() -> SyntaxContext::root() 
For consistency with `ExpnId::root`.

Also introduce a helper `Span::with_root_ctxt` for creating spans with `SyntaxContext::root()` context

Rollup merge of #62984 - nathanwhit:extra_semi_lint, r=varkor 
Add lint for excess trailing semicolons

Closes #60876.
A caveat (not necessarily a negative, but something to consider) with this implementation is that excess semicolons after return/continue/break now also cause an 'unreachable statement' warning.

For the following example:
```
fn main() {
    extra_semis();
}
fn extra_semis() -> i32 {
    let mut sum = 0;;;
    for i in 0..10 {
        if i == 5 {
            continue;;
        } else if i == 9 {
            break;;
        } else {
            sum += i;;
        }
    }
    return sum;;
}
```
The output is:
```

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.
