[Bug tree-optimization/28905] [4.2 regression] ICE in compare_name_with_value, at tree-vrp.c:3557

Confirmed, but it looks unrelated to that PR but rather a change from SCEV
might had caused this.
Reduced testcase:
void f(void) __attribute__ ((noreturn));
int g(void);
void code_comment (void)
{
  int size = g();
  for (int i = 0; i < size; i++)
    {
      int n = i;
  if (n)
    {
        if (n < 0)
          if (n < 0)
            f ();
    }
    }
}

Janis,
  Could you do a regression hunt for this one?
Thanks,
Andrew
