[X86][AVX] canonicalizeShuffleMaskWithHorizOp - improve support for 256/512-bit vectors
Extend the HOP(HOP(X,Y),HOP(Z,W)) and SHUFFLE(HOP(X,Y),HOP(Z,W)) folds to handle repeating 256/512-bit vector cases.
This allows us to drop the UNPACK(HOP(),HOP()) custom fold in combineTargetShuffle.
This required isRepeatedTargetShuffleMask to be tweaked to support target shuffle masks taking more than 2 inputs.
