> Original change's description:
> > [heap] Fix conservative stack scanning for client isolates
> >
> > With this CL, the context of stacks corresponding to all client isolates
> > are saved, so that conservative stack scanning can be used correctly
> > during a shared garbage collection. This happens:
> >
> > 1) in Heap::PerformSharedGarbageCollection, for the stacks of the shared
> > isolate and the initiator;
> > 2) when an isolate's main thread is waiting in a safepoint; and
> > 3) when an isolate's main thread is parked.
