 // Mark-sweep old-space.
 // * Uses worst-fit free-list allocation to get big chunks for fast bump
 //   allocation.
 // * Non-moving for now.
 // * Has on-heap chained data structure keeping track of
 //   promoted-and-not-yet-scanned areas.  This is called PromotedTrack.
 // * No remembered set yet.  When scavenging we have to scan all of old space.
 //   We skip PromotedTrack areas because we know we will get to them later and
 //   they contain uninitialized memory.
