Nuno Lopes dd995aceda [InstCombine] remove incorrect gep(x, undef) -> undef optimization ... gep(x, undef) carries the provenance of x, so we can't replace it with any pointer like undef. This leaves room for improvement for the poison case, but that's currently not possible as the demanded bits API doesn't distinguish between undef & poison bits.
