Simon Pilgrim 85ebf04519 [X86][SSE] Replace combineShuffleWithHorizOp with canonicalizeShuffleMaskWithHorizOp 
Instead of just attempting to fold shuffle(HOP,HOP) for a specific target shuffle, make this part of combineX86ShufflesRecursively so we can perform this on the combined shuffle chain, which is particularly useful for recognising more cases of where we're performing multiple HOPs that can be merged and pre-AVX where we don't have good blend/unary target shuffle support.
