_reduce(): 

- Fix for SF bug #482752: __getstate__ & __setstate__ ignored (by Anon.)

    In fact, only __getstate__ isn't recognized.  This fixes that.

  - Separately, the test for base.__flags__ & _HEAPTYPE raised an
    AttributeError exception when a classic class was amongst the
    bases.  Fixed this with a hasattr() bandaid (classic classes never
    qualify as the "hard" base class anyway, which is what the code is
    trying to find).
