[Bug tree-optimization/34677] PREs insert_fake_stores is mostly useless

I think the other PR is only about VN global constants.  But also an incoming
pointer to a structure is not handled:

struct X { int i; };
int foo(struct X *a, int argc)
{
  int b;
  int c;
  int i;
  int d, e;

  for (i = 0; i < argc; i++)
    {
      e = a->i;
      a->i = 9;
    }
  return d + e;
}
