This will allow us (later) to make nice descriptions of the state of an isolate, e.g. "isolate 7112 is paused due to breakpoint 2" or "isolate 7112 is paused due to interrupt" or "isolate 7112 is running". Use a new Pause() function to call the event handler during a pause. It does some shared checking, setup, teardown. Minor change in isolate interrupt handling - before we were not setting 'in_event_handler_' in this case. Now we set 'pause_event_' here, which will guard against recursive pauses in this case. Reviewer: not sure what I think about all the names I used here. "pause_event_" is very similar to PausedEvent but means something different, as it includes pauses, interrupts, and (maybe) exceptions. Dunno.
