8022817: CMS should not shrink if compaction was not done

If UseCMSCompactAtFullCollection is turned off, a full GC that is done in the foreground but does not compact should not shrink the generation. In that case a mark-sweep was done so the free space is maintained in freelists (not as a contiguous area at the end of the generation) and shrinking for freelists is not implemented.

Thanks.
