      Description

      Currently, only the card sets (remembered sets) use G1CardSetFreePool to give back memory to OS.

      After JDK-8254739, this memory reclaiming mechanism could be reused by evacuation failure too. This is a preparation change to allow reuse of this code.

      I plan to do this in about 3 steps to smooth the review process:
        1. move G1CardSetFreePool and related classes to new file, rename these classes
        2. refactor these classes to support freeing other freelist
        3. some necessary cleanup
