Confirmed, here is a testcase which makes sure that we don't have to worry 
about the one use property 
of forwprop:
enum tree_code {
  AAA,
  BBB,
  CCC
};

struct tree_common {
  enum tree_code code : 8;
};

int
foo (struct tree_common *p)
{
  enum tree_code code = p->code;
  if (code == 0)
    return 1000;
  return 123;
}
