For correct slots recording in concurrent marker, we need to resolve the race that happens when 1) the mutator is invalidating slots for double unboxing or string conversions 2) and the concurrent marker is recording these slots. This patch adds a data-structure for tracking the invalidated objects. Thus we can allow the concurrent marker to record slots without worrying about clearing them. During old-to-old pointer updating phase we re-check all slots that belong to the invalidated objects.
