* 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.

* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
attribute reference does not denote a subtype, it can be any

dereference. In particular, the prefix can be a view conversion for
a classwide type (for which Is_Object_Reference holds), but it can
also be a value conversion for an access-to-classwide type. In the
latter case, there is an implicit dereference, and the original node
for the prefix does not verify Is_Object_Reference.
