this change adds an event, vm/gc/detailed/class_count_after_gc, that
sends information about the number of instances of each class on the
heap (as well as size and the name of the class).
The event is sent after the marking phase for all old collections and an
object will be counted as live if the GC think that the object is live
(this is only tricky in the case of a concurrent collection).
