[PATCH] D42948: [SelectionDAG] Support some SimplifySetCC cases for comparing against vector splats of constants.

We're not checking isCondCodeLegal consistently. The only calls to it are in the two blocks that covered with !isVector. I'm not sure we can use isCondCodeLegal correctly with SSE/AVX and AVX512 having different behaviors.
