      Description

      In JDK-7145569 per-region code root remembered sets were introduced.

      However these per-region remembered sets are not accounted for in the region efficiency.

      I.e. G1CollectorPolicy::predict_region_elapsed_time_ms() does not take this into account.

      This negatively affects pause time prediction performance
