come from the runtime. This patch fixes an issue of heap growing to max capacity when incremental marking is finished but cannot finalize due to GC stack guard not triggering. It can happen if all allocations come from the runtime, for example, from JSON parser or compiler. Now before expanding the heap we check if we are above the allocation limit and the incremental marking needs to be finalized. If so we do not expand the heap and force GC, which will finalize the incremental marking. The check is performed for paged spaces and large-object space.
