What? I see only free functions, like _Rb_tree_increment, and pointers to types
like _Rb_tree_node_base. But I see that probably you just had a typo in your
original message, you meant that the _Rb_tree_increment(_Rb_tree_node_base*)
call is not inlined in _Rb_tree_increment(const _Rb_tree_node_base*).

Still, I don't see *what* really changed post-Benjamin split and *why*. Jakub
may have already figured out that, I don't.
