RFR: 8311163: Parallel: Improve large object handling during evacuation

[Kim Barrett]

Please review this change to ParallelGC young generation collection's handling
of large objArrays, to now use the infrastructure provided by JDK-8253237 and
JDK-8337709.  (That's the same infrastructure used by G1 young/mixed
collections.)

Testing: mach5 tier1-5
