…h-pat-only, r=petrochenkov Validate that we're only matching on unit struct for path pattern Resolution doesn't validate that we only really take `CtorKind::Unit` in path patterns, since all it sees is `Res::SelfCtor(def_id)`. Check this instead during pattern typeck. r? petrochenkov Fixes rust-lang#122809
