A MarkedValueList is basically a Vector<JS::Value> that registers with the Heap and makes sure that the stored values don't get GC'd. Before this change, we were unsafely keeping Vector<JS::Value> in some places, which is out-of-reach for the live reference finding logic since Vector puts its elements on the heap by default. We now pass all the JavaScript tests even when running with "js -g", which does a GC on every heap allocation.
