Dominik Inführ e79d34ee36 [heap] Slots are either in sweeping or old-to-new RS after Full GC
This CL ensures that recorded slots are either in the sweeping or the
old-to-new remembered set after mark-compact depending on whether the
page was already swept or not.

All pages that are swept during the evacuation phase also have their
remembered sets merged. is_local() is renamed to
is_compaction_space() and non-virtual. The PagedSpace now not only
knows whether it is a compaction space or not but also for which
collection through the compaction_space_kind_ field. This allows
RefillFreeList to merge the remembered sets immediately also for the
mark-compact collection.
