Optimize locale::_M_impl->_M_names for the most common cases:
!_M_names[0] means unnamed; !_M_names[1] means all the categories
the same name (_M_names[0] && _M_names[1] means that the full set
of _M_names must be processed, the general case).

Tweak, saving work when !_M_names[1].
(locale::locale(const locale&, _Facet*): Simplify: now just setting
_M_names[0] = 0 means unnamed.
* src/locale.cc (locale::operator==): Deal first with the common,

(locale::_Impl::_M_replace_categories): When !_M_names[1] prepare
for the general case (full set of names), then do the usual work;
clean up.
* src/locale.cc (locale::name()): Reserve space in __ret.

* 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.
