Remove manual selection code for this intrinsic and use a GISelPredicateCode instead.

      

This allows us to fully select this intrinsic without any tricky custom C++ matching for small types.

This is dependent on D65756 <https://reviews.llvm.org/D65756>, since these intrinsics use llvm_anyptr_ty.
