Fixup for #13223, two things:
normalize_projection_query()
(and consequentlyHirDatabase::normalize_projection()
) never returnsNone
(well, it used to when I first wrote it...), so just returnTy
instead ofOption<Ty>
normalize_trait_assoc_type()
used to returnNone
before fix: handle lifetime variables in projection normalization #13223, but not anymore because of the first point. I restored the behavior so its callers work as before.
