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.

a3923ce210 [heap] Implement simple marking in the concurrent marking thread. 
The concurrent marker uses ObjectVisitor to iterate pointers in objects
and local marking bitmaps to keep track of visited objects.

To keep it simple for now, I removed support for multiple tasks
and canceling unfinished tasks.
