[CodeGen,Target] Remove the version of DAG.getVectorShuffle that takes a pointer to a mask array. Convert all callers to use the ArrayRef version. No functional change intended.

For the most part this simplifies all callers. There were two places in X86 that needed an explicit makeArrayRef to shorten a statically sized array.
