  [X86] Add test coverage for permilps with freeze

Its going to be easier to add some basic target shuffle handling than generic ISD::SHUFFLE_VECTOR nodes which is going to need special handling for unused/undef operands.

Both freeze_pshufd and freeze_permilps tests lower to vpermilps, but only in domain switching later on.

  [X86] Add freeze(pshufd/permilps(x,imm)) -> pshufd/permilps(freeze(x),imm) folding

Add X86 isGuaranteedNotToBeUndefOrPoisonForTargetNode / canCreateUndefOrPoisonForTargetNode overrides and add X86ISD::PSHUFD/VPERMILPI handling.
