I don't think we can remove _GLIBCXX_READ_MEM_BARRIER and

I see. We should at least update the documentation of those, as the
current one isn't a really portable specification. If we can, I'd
deprecate them. Jonathan, what do you think?
Yes, I'm in favour of deprecating them. They are GCC-specific anyway,
so there is no reason to prefer them to std::atomic_ or __atomic_
fences.
