Clairify `ast::PatKind::Struct` presese of `..` by using an enum instead of a bool The bool is mainly used for when a `..` is present, but it is also set on recovery to avoid errors. The doc comment not describes both of these cases. See https://github.com/rust-lang/rust/blob/cee794ee98d49b45a55ba225680d98e0c4672736/compiler/rustc_parse/src/parser/pat.rs#L890-L897 for the only place this is constructed. r? ``@compiler-errors``
