I think this only needs a library interface, at least when we're just
considering the __atomic builtins.  On the C/C++ level, it might amount
to just another atomic type, which only has a CAS however; this could be
probably modelled entirely through default atomics (not implemented
though), and so wouldn't need a language or memory model extension.
