RFR (S): 8076463: Add logging for the preserve CM referents task

[Tom Benson]

Looks good to me as well.

Completely aside, there are enough 
"WorkerDataArray<double>(max_gc_threads,..." instances in g1GCPhaseTimes 
that it might be nice to have a convenience class that is a double 
WorkerDataArray of size max_gc_threads. ParPhaseTimesArray, or something.
