      [heap] Add mechanism for tracking invalidated slots per memory chunk. · 7a5a777c
      Ulan Degenbaev authored
      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.
