--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So in this case, ifcombine can combine:
  if (!__cond60)
    {
      if (__cond59)
        {

Into:

(!__cond60) & __cond59

Yes the rhs will be unitialized but if __cond60 is true but that should not
cause wrong code.  There is something else going wrong here than my patch.
