[InstCombine] Don't sink if it would require dropping deref assumptions. (#166945)
Currently sinking assumes in instcombine drops assumes if they would
prevent sinking. Removing dereferenceable assumptions earlier on can
inhibit vectorization of early-exit loops in practice.
Special-case deferenceable assumptions so that they block sinking. This
can be combined with a separate change to drop dereferencebale
assumptions after vectorization: https://clang.godbolt.org/z/jGqcx3sbs
