  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp

  Log Message:
  -----------
  [TargetLowering] expandCTPOP don't create an used constant mask for i8 ctpop. NFC

Use early out for the i8 case.

I'm looking at avoiding MUL on targets that use libcalls for MUL.
So doing a little pre-refactoring.
