Following on from bug 1585921, we should document what the correct/recommended barriers are for GC hash tables and then try to enforce this statically as best we can.

One issue is for atom keys. Previously I think we advised using HeapPtr for these, but now that strings can be nursery allocated these have a post barrier which will execute even though atoms are never nursery allocated. So it works, it's slightly inefficient, but mainly it worries me that we're even considering updating atom keys.
