[Bug tree-optimization/113302] `x == 1 ? 1 : (x == -1 ? -1 : 0)` should be optimized to `((unsigned)t) + 1 <= 2 ? 0`

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This should also optimize to that:
```
int j(int x)
{
  int t = x == -1;
  int t1 = x == 1;
  return t | -t1;
}
```
