I think after remove empty loops, we should add a DCE pass which should fix the
above reduced testcase but will not fix this reduced testcase:
int length1();
int g(int);
void f(int capacity_, char*old_storage)
{
  try {
    length1();
    int old_capacity = capacity_;
    capacity_ *= 2;
    g(capacity_);
    for (int i = 1; i < old_capacity; i++)
     old_storage[i] = old_storage[i - 1];
  } catch (...) {
    for (int i = 1; i < capacity_; i++){old_storage[i] = 0;}
  }
}
