ulan 3477957ecd [heap] Start concurrent marking simultaneously with incremental marking.
This patch hooks up concurrent marking (behind the flag) with the rest
of the GC:
1. Incremental marking spawns concurrent marking task seeded with the
root set.
2. Mark-compact waits for concurrent marking tasks to finish.
3. Scavenger does fast promotion if concurrent marking is pending.
