The intrinsic itself is still unstable so it can't be called from stable code; this just affects whether stable const fn inside core/std can call this intrinsic. LGTM!

There is a test for this, right? Just double checking.

It's a regular unstable intrinsic. I don't think we need a test for each unstable intrinsic that it can't be called from stable.

Whether we have a test for the general situation of "unstable but const-stable item", I do not know. The machinery for that is not new.
