      Description

      In JDK-8220465 shadow regions were added as an optimization to increase parallelism in the full gc algorithm.

      In psParallelCompact.hpp there is a comment explaining the handling when space is scarce and live data of a source region is copied to multiple spaces.

      Some note about how/if this interacts with shadow regions should be added here.
