[X86] canonicalizeShuffleWithBinOps - handle general unaryshuffle(binop(x,c))... 

[X86] canonicalizeShuffleWithBinOps - handle general unaryshuffle(binop(x,c)) patterns not just xor(x,-1)

Generalize the shuffle(not(x)) -> not(shuffle(x)) fold to handle any binop with 0/-1.

Hopefully we can further generalize to help push target unary/binary shuffles through binops similar to what we do in DAGCombiner::visitVECTOR_SHUFFLE
