7050392: G1: Introduce flag to generate a log of the G1 ergonomic decisions
Summary: It introduces ergonomic decision logging in G1 for the following heuristics: \
heap sizing, collection set construction, concurrent cycle initiation, and \
partially-young GC start/end. The code has a bit of refactoring in a few places to \
make the decision logging possible. It also replaces alternative ad-hoc logging that \
                we have under different parameters and switches (G1_DEBUG, \
                G1PolicyVerbose).

4965777: GC changes to support use of discovered field for pending references
Summary: If and when the reference handler thread is able to use the discovered field \
to link reference objects in its pending list, so will GC. In that case, GC will scan \
through this field once a reference object has been placed on the pending list, but \
not scan that field before that stage, as the field is used by the concurrent GC \
thread to link discovered objects. When ReferenceHandleR thread does not use the \
discovered field for the purpose of linking the elements in the pending list, as \
would be the case in older JDKs, the JVM will fall back to the old behaviour of using \
                the next field for that purpose.

7084509: G1: fix inconsistencies and mistakes in the young list target length \
                calculations
Summary: Fixed inconsistencies and mistakes in the young list target length \
calculations so that a) the calculated target length is optimal (before, it was not), \
b) other parameters like max survivor size and max gc locker eden expansion are \
always consistent with the calculated target length (before, they were not always), \
and c) the resulting target length was always bound by desired min and max values \
                (before, it was not).
