[Bug middle-end/33423] [4.2/4.3 regression]: internal compiler error: in expand_expr_real_1, at expr.c:8670

Another simple testcase:
---
static char buf;

void
test6 (void)
{
  int len;
  void *p;

  for (len = 0; len < 2; len++)
    {
      p = __builtin___memset_chk (&buf, '\0', len, 1);
      if (p != &buf) return;
    }
}
---

fold_builtin_memset was added to return COMPOUND_EXPR via
omit_one_operand. But there was nothing added to handle it.
