Bug 1573458 - Leave the atoms zone when performing a GC r=tcampbell Entering the atoms zone with AutoAllocInAtomsZone is a bit of a special case and we don't support entering another realm in this state. Unfortunately this can happen during GC in a couple of place. The patch temporarily leaves the atoms zone during GC so that callbacks can enter whatever zones they like.
