  some notes:

- the GCPauseTimer class can be removed now too I think. This change
removes its last uses.

- in CMSCollector::reset(), I am not sure why the
AdaptiveSizePolicyOutput use has been removed, and the change in
AdaptiveSizePolicyOutput::print_test(). Same in
GenCollectedHeap::do_collection(). If that is intendeded, can we remove
the local "sp" variable in CMSCollector::reset(), i.e. inline it? It's
only used once quite far below.
That's just a suggestion, I am fine with either way.

Otherwise looks good.

Thanks,
Thomas
