--- Comment #3 from Jeffrey A. Law <law at redhat dot com> ---
 if (_8 != _14)
    goto <bb 3>;
  else
    goto <bb 6>;

  <bb 3>:
  target_bb.1_15 = target_bb;
  if (_14 == target_bb.1_15)
    goto <bb 4>;
  else
    goto <bb 6>;

  <bb 4>:
  if (_8 != target_bb.1_15)
    goto <bb 5>;
  else
    goto <bb 6>;


Presumably depending on the ordering in the conditionals, we should discover
that in bb4 _8 and _15 are equal and eliminate the test.
