Um. I don't understand why did we drop "Drain Queues", and do this:

 policy->record_phase_start(full_gc ?
      ShenandoahCollectorPolicy::full_gc_mark_drain_queues :
      ShenandoahCollectorPolicy::drain_satb);

I would have expected we keep "Drain Queues", and drop "Drain SATB"
counters, because we still do queue work.

Thanks,
