	* include/bits/cpp_type_traits.h: Changed __is_pod
	completely. Now, it does not use any of the previous type_traits
	to detect the pod types, and it also detects function pointers as
	POD types.

	* include/bits/stl_tree.h: Introduced a new class _Rb_tree_impl,
	which encapsulates the internal implementation of an rb_tree. Made
	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.
