I updated the webrev after some helpful comments from Andrey
Petrusenko (thank you Andrey).

The only files changed were collectedHeap.[ch]pp--I removed some
static constants in favor of inlined methods and shortened the method
CollectedHeap::fill_with_objects().

If anyone else is looking at this webrev, let me know and I'll wait.
Otherwise, I will push tomorrow after some testing overnight.
