  unsigned long long __builtin_cntlzdm (unsigned long long, unsigned long long)
  unsigned long long __builtin_cnttzdm (unsigned long long, unsigned long long)
  vector unsigned long long vec_cntlzm (vector unsigned long long, vector unsigned long long)
  vector unsigned long long vec_cnttzm (vector unsigned long long, vector unsigned long long)

Depends on D80935 <https://reviews.llvm.org/D80935>
