the allocator a base class of this class instead of the rb_tree,
which was not conforming. This _Rb_tree_impl class is also
specialized on whether the _Compare parameter is a POD type or
not. If so, then it maintains the comparison function as a data
member, otherwise it makes the _Compare parameter a base class of
itself. Also, _M_key_compare is now a function instead of a data
member, so that the above trick can work properly. Delegated the
initialization of the other data members to this newly created
class. Also, now other member functions of rb_tree must refer to
_M_key_compare as _M_impl._M_key_compare(). The other data members
(*) can be referenced to as _M_impl.(*), where
(*) includes _M_header, and _M_node_count.
