  [X86] combineTargetShuffle - cleanup PSHUFD/LW/HW folds (#225477)

Handle all PSHUFD/LW/HW folds in the main switch statement - we
simplified the combineRedundantDWordShuffle folds ages ago, but never
merged the 2 switch statements back together.

The isNoopShuffleMask check should have already been taken care of by
combineShuffle.
