Yes. Covering array profile is in my TODO list, just not done yet.

Also I realized that all my existing benchmarks are single typed. I have 
to run it with and without profiles. Are options -XX:-UseACmpProfile 
-XX:-UseTypeSpeculation -XX:-UseArrayLoadStoreProfile enough to turn off 
all profiling?
