[X86] Handle undef/zero/ones cases after modifying Ops and Masks (#158428)
Fixes https://github.com/llvm/llvm-project/issues/158415.
After `resolveTargetShuffleInputsAndMask` and other modifications on
`Ops` and `Mask`, unused inputs in `Ops` are erased, and may leave `Ops`
empty. This patch handles such cases before calling the final
`combineX86ShuffleChain`。
