A LocalHeap creates and owns an instance of MarkingBarrier. A pointer to the marking barrier is set to a thread_local variable for a quick access. WriteBarrier::MarkingSlow fetches the thread_local variable and invokes the write barrier if it is set. Otherwise, it invokes the main thread heap()->marking_barrier(). Each marking barrier has its own local marking worklist that is published during scavenge (for updating pointers) and at finalization of incremental marking. Typed-slot recording does not work yet because it is not thread-safe. It will be fixed in a subsequent CL.
