Bring back old fallback semantics: Without feature(never_type), fallback to `()`, not `!`.
Note that this commit, since it is trying to be minimal in order to ease backporting to the beta and release channels, does *not* include the old future-proofing warnings that we used to have associated with such fallback to `()`; see discussion at this comment: https://github.com/rust-lang/rust/issues/49691#issuecomment-381266730
