[X86][SSE] Combine EXTRACT_VECTOR_ELT with combineExtractWithShuffle before XFormVExtractWithShuffleIntoLoad
combineExtractWithShuffle can handle more complex shuffles/bitcasts than we can with the equivalent code in XFormVExtractWithShuffleIntoLoad.
Mainly a compile time improvement now (combineExtractWithShuffle combines will have always failed late on inside XFormVExtractWithShuffleIntoLoad), and will let us merge combineExtractVectorElt_SSE in a future commit.
