Pushing the CollectorPolicy cleanup patch set

[Stefan Karlsson]

Hi all,

Just a heads up: I now have reviews for the following patches:

8198530: Move _gc_policy_counters from GenCollectorPolicy to GenColle
8198528: Move GenerationSpecs from GenCollectorPolicy to GenCollected
8198525: Move _size_policy out of GenCollectorPolicy into GenCollecte
8198515: Extract SoftReferencePolicy code out of CollectorPolicy
8198511: Move allocation functions from GenCollectorPolicy to GenColl
8198509: Move satisfy_failed_metadata_allocation out from CollectorPo
8198507: Remove CollectorPolicy::create_rem_set
8198373: Remove CollectorPolicy::is/as functions

and I'm going to push this when/if testing passes.

Thanks,
StefanK
