It is weird. I think it cannot fix the warning.

See the users of matchSelectFromAndOr:
```
      if (Value *V = matchSelectFromAndOr(A, C, B, D))
        return replaceInstUsesWith(I, V);
      if (Value *V = matchSelectFromAndOr(A, C, D, B))
        return replaceInstUsesWith(I, V);
      if (Value *V = matchSelectFromAndOr(C, A, B, D))
        return replaceInstUsesWith(I, V);
      if (Value *V = matchSelectFromAndOr(C, A, D, B))
