261e7583ab 8069330: Adjustment of concurrent refinement thresholds does not take hot card cache into account
Measure HCC processing time separately and remove that time from the calculation of the refinement thresholds. HCC processing time is still taken into account for general pause time predictions.

afb458ef0e 8048179: Early reclaim of large objects that are referenced by a few objects
Push the remembered sets of large objects with few referenced into the dirty card queue at the beginning of the evacuation so that they may end up with zero remembered set entries at the end of the collection, and are potentially reclaimed. Also improve timing measurements of the early reclaim mechanism, and shorten flag names.
