Client isolates need the incremental marking barrier for objects in
the shared heap. The marking barrier for the shared heap can be
enabled either with or without incremental marking in the client
isolate's local heap.
Client isolates get a new marking worklist in the MarkingBarrier
class for marking of shared objects. Shared objects will always be
pushed into that worklist for tracing. MarkingBarrier can be enabled
for shared marking and/or marking of local isolates.
