  Log Message:
  -----------
  [X86][SSE] matchShuffleWithSHUFPD - add support for unary shuffles.

This causes one minor test change but is mainly necessary for an upcoming patch.

  Log Message:
  -----------
  [X86][SSE] getFauxShuffleMask - add support for INSERT_VECTOR_ELT(EXTRACT_VECTOR_ELT) shuffle pattern

We already do this for PINSRB/PINSRW and SCALAR_TO_VECTOR.
