  [X86] combineConcatVectorOps - add handling for X86ISD::VSHL/VSRL/VSRA

These can be handled the same as the vector shift by immediate variants that are already handled.

  Log Message:
  -----------
  [X86] combineConcatVectorOps - remove superfluous Subtarget.hasAVX() check

This function only ever gets called by AVX targets, and we already assert for this at the top of the function
