[X86] combineConcatVectorOps - add handling for X86ISD::SHUF128 nodes. 

Prevents regression on some future work to improve codegen for concat_vectors(extract_subvector(),extract_subvector()) patterns.

X86ISD::SHUF128 optimization is still pretty poor (especially the zmm variant), not optimizing the shuffle demanded elts like we do for SHUFPS.
