Even though @AdvenamTacet will be back in a few days (May 9th), it's unlikely that a quick fix is possible here. Because of that, merging this PR right now is OK. I don't mind reverting the `__annotate_memory_barrier` parts anyway, as we probably need to get rid of them regardless. With the barriers gone, the rest of the revert is just a few lines of code that we can easily reintroduce later once we have a proper solution.

I hope we can reland it under a separate libc++ option in future. That way, we won't have to disable the stable long-string annotations just because of issues with the short ones.
