ac037c1359 Recover from missing semicolon based on the found token 
When encountering one of a few keywords when a semicolon was
expected, suggest the semicolon and recover:

```
error: expected one of `.`, `;`, `?`, or an operator, found `let`
  --> $DIR/recover-missing-semi.rs:4:5
   |
LL |     let _: usize = ()
   |                      - help: missing semicolon here
LL |
LL |     let _ = 3;
   |     ^^^

error[E0308]: mismatched types
  --> $DIR/recover-missing-semi.rs:2:20
   |
LL |     let _: usize = ()
   |                    ^^ expected usize, found ()
   |
   = note: expected type `usize`
              found type `()`
```

Rollup merge of #59266 - estebank:struct-parse-recovery, r=petrochenkov 
Do not complain about non-existing fields after parse recovery

When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.

Fix #57361.

Rename variadic to c_variadic 
Function signatures with the `variadic` member set are actually
C-variadic functions. Make this a little more explicit by renaming the
`variadic` boolean value, `c_variadic`.
