I see there are still a few instances below where we return the result of `addUse` as a boolean result, but it should really have one more method call to `constrainAllUses` at the end as should the ones below. 
```suggestion
      .addUse(I.getOperand(2).getReg())
      .constrainAllUses(TII, TRI, RBI);
```
