G1CollectorPolicy contains copies of the linked list heads and tails
present in YoungList.
In order to reduce the size of the G1CollectorPolicy, I suggest we
remove them and have the policy access the ones in YoungList instead.
Testing: JPRT (including runs with assertions that the pointers and
lenght are in fact equal)
