    Description

      Need to factor out the existing IHOP threshold calculation into a separate class to allow more complex (adaptive) algorithms on demand.

      Collect data needed for IHOP calculation and feed it to this class.

      Refactor young list target length calculation for G1CollectorPolicy to use less global state.

      This is required to accomodate dIHOP changes.
