I agree with the sentiment that this needs a test. However, based on my discussion with @dalg24  just now, I fail to see how the test helper can be modified to accommodate that. Given that, I think it's acceptable to move forward with the patch despite not having great "runtime behavior" coverage for `atomic_ref<const T>`.

If you have ideas for changing the test driver, please let us know.
