  Log Message:
  -----------
  [X86] combineLoad - allow constant loads to share matching 'lower constant bits' with larger VBROADCAST_LOAD/SUBV_BROADCAST_LOAD nodes

We already had separate support for VBROADCAST_LOAD - merge this with the generic load handling and add SUBV_BROADCAST_LOAD support as well.
