[Bug tree-optimization/8781] Pessimization of C++ (functional) code

The real problem can be seen with:
int f(void);
int h(void);

int g(int a)
{
  int (*ff)(void) = f;
  int (**g)(void);
  g = &ff;

  (*g)();
  h();
  (*g)();
}

we mark the value which we calling as escaping:
D.1289_5, is dereferenced, its value escapes, points-to anything
D.1289_6, is dereferenced, its value escapes, points-to anything

that is wrong.
