Ian Lance Taylor cfe3cd903f runtime: keep P's first timer when in new atomically accessed field 
This reduces lock contention when only a few P's are running and
checking for whether they need to run timers on the sleeping P's.
Without this change the running P's would get lock contention
while looking at the sleeping P's timers. With this change a single
atomic load suffices to determine whether there are any ready timers.
