[Bug middle-end/39666] spurious warning with ranged-switch statements

In C:

int foo (int i)
{
  int j;
  switch (i)
    {
    case -__INT_MAX__ - 1 ... -1:
      j = 6;
      break;
    case 0:
      j = 5;
      break;
    case 1 ... __INT_MAX__:
      j = 4;
      break;
    }
  return j;
}

fails the same way.  The default label is added by gimplify_switch_expr.
