See simplify_type

Note that we keep this type generic over the type of identifier it uses because we sometimes need to use SimplifiedTypeGen values as stable sorting keys (in which case we use a DefPathHash as id-type) but in the general case the non-stable but fast to construct DefId-version is the better choice.
