[X86][SSE] canonicalizeShuffleWithBinOps - check for more combos of merge-able binary shuffles. In the fold SHUFFLE(BINOP(X,Y),BINOP(Z,W)) -> BINOP(SHUFFLE(X,Z),SHUFFLE(Y,W)), check if both X/Z AND Y/W have at least one merge-able shuffle in which case the total number of shuffle should still fall. Helps with instruction count regressions we saw while fixing PR48823 GitOrigin-RevId: 4fbe7615721863c57b4fd4334f361a5d4157e235
