I like the idea. I'm a bit wary of using a non-aarch64-namespaced name for the variable, but it looks like it could be useful for other targets testing if they wished to. In any case, as it's internal-only and non-documented we won't make any promises on its compatibility. So ok if the testsuite parts are approved.
