This reverts commit c59b81d7b8.
Original change's description:
> [heap] Add mechanism for tracking invalidated slots per memory chunk.
> 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.
