Reduce ULE context switch time by over 25%.

 - Only calculate timeshare priorities once per tick or when a thread is woken
   from sleeping.
 - Keep the ts_runq pointer valid after all priority changes.
 - Call tdq_runq_add() directly from sched_switch() without passing in via
   tdq_add().  We don't need to adjust loads or runqs anymore.
 - Sort tdq and ts_sched according to utilization to improve cache behavior.
