Description
Right now, at the end of a GC pause, we redirty cards of survivor and scan-only regions serially. It'd be good to do it in parallel. In fact, we should be able to piggyback onAndrey's recent changes for 6819065. Said changes clear the card table of regions in parallel; it should be straightforward to extend that code to also redirty regions.
