LockGuard is mostly used with Mutex. Since both are defined outside the internal namespace, we often have to write {base::LockGuard<base::Mutex>}.

When marking ephemerons visit individual ephemerons with key and value unreachable instead of simply iterating all ephemerons in all weak collections. Also visit ephemerons at end of concurrent marking to do work we would otherwise need to do in the atomic pause.

JSWeakCollections used to be chained in a singly-linked list. The GC now stores the JSWeakCollection's backing store EphemeronHashTable in a Worklist. This should allow easier parallelization in the future.

When hitting objects that are allocated in the most recent lienar allocation area, the concurrent marker currently has to bail out to the main thread. However, we only have to delay processing those objects until we are at a safepoint, e.g. IM::Step(). With this change we flush those on-hold-objects back to the shared queue upon performing an incremental marking step.

This patch makes the check lock-free. When concurrent marking is on, the main thread checks two marking worklist: bailout and shared. Often the bailout worklist empty, so the emptiness check is in hot path.

Replaces the old PromotionQueue that was kept at the end of to space. This change allows a future implementation to use (a) a thread-local promotion list and (b) enables work stealing for concurrent scenarios.
