I added OptimizeFill to this webrev and removed the code to turn it on from arguments.cpp.
I filed a bug a while to turn on EliminateAutoBox but I also wanted to move some code out from under that flag that wasn't strictly part of that functionality. That's http://cr.openjdk.java.net/~never/6934604. I'd like to push that after we see how the nightlies look after turning on the others.
