      Description

      JDK-8027295 observes that the Free CSet phase of young gen GC on large heaps takes a significant amount of time.

      There is a prototype that improves the serial performance by tweaking the code, and another one based on the former parallelizing parts of this phase.

      This CR is a split-out of the parallelization efforts. The changes in JDK-8027295 are prerequisites for parallelization.
