Won't that disable the warning in the valid cases though?

int
f2 (int R)
{
  int i, inter[3];

  for (i = 1; i < R; i++)
    {
      inter[0] = 1;
      inter[1] = 1;
      inter[2] = 1;
    }

  return inter[0];
}

I've tried apparently doesn't warn even without the change, because ccp for a
PHI which has undefined SSA name and defined SSA name just propagates the
defined one (without a warning), so I don't have a testcase.
