* include/bits/shared_ptr.h: Update comparisons to match WP.
(_Sp_counted_ptr): Make copy and assignment members deleted.
(_Sp_counted_deleter): Remove private copy and assignment members.
(__shared_count::_M_less,__weak_count::_M_less,operator<): Replace
friend operator< with overloaded _M_less member functions to allow
comparison with either shared_count or weak_count.
(__shared_ptr::_M_less,__weak_ptr::_M_less): Replace with...
(__shared_ptr::owner_before,__weak_ptr::owner_before): New overloads
for ownership-based ordering.
(operator<(__shared_ptr,__shared_ptr)): Compare stored pointers,
make non-friend.
(operator==(__shared_ptr,__shared_ptr)): Make non-friend.
(operator!=(__shared_ptr,__shared_ptr)): Likewise.
(less<__shared_ptr<>>,less<shared_ptr<>>,_Sp_less): Explicitly call
pointer specialization.
(__weak_ptr::operator<,weak_ptr::operator<=,weak_ptr::operator>,
weak_ptr::operator>=): Remove operator< and delete all comparisons.
(_Sp_owner_less,owner_less): Predicate for ownership-based ordering.
(operator<(shared_ptr,shared_ptr): Overload for derived shared_ptr.
(operator==(shared_ptr,shared_ptr): Likewise.
(operator!=(shared_ptr,shared_ptr): Likewise.
(swap(shared_ptr,shared_ptr)): Fix parameter types.
(swap(weak_ptr,weak_ptr)): Add missing overload.
