rev 5920 : 8035406: Improve data structure for Code Cache remembered sets
Summary: Change the code cache remembered sets data structure from a GrowableArray to a chunked list of nmethods. This makes the data structure more amenable to parallelization, and decreases freeing time.

rev 5922 : 8035398: Add card redirty time in "Other" time in G1
Summary: Show the time taken by card redirtying during GC in a new "Redirty Cards" line.
