My preference would be to do it like that rather than adding yet
another level of indirection to our atomics.

The shared_ptr refcounts in bits/boost_sp_counted_base.h should be
able to use the same approach for _M_release and _M_weak_release, but
I'm not sure about the compare-and-swap loop in _M_add_ref_lock
