This fix looks not in a proper direction. If I remove lines `llvm/trunk/lib/Target/PowerPC/PPCInstrInfo.cpp:[2259-2261)` in https://reviews.llvm.org/D56078, the test in this patch gets passed.
I tried dump `MI` and its `explicit_operands`, the output looks not what I expected.
Code modification

  if (SpecialShift32 || SpecialShift64) {
    MI.dump();
    for (auto &op : MI.explicit_operands()) {
      op.dump();
    }

Output

    renamable $x4 = exact RLDICL killed renamable $x4, killed renamable $r5, implicit $x5
  renamable $x4
  killed renamable $x4
  killed renamable $r5
  implicit $x5

`implicit $x5` is in the explicit operand list.
