Summary Support DOM memory usage estimation

It would be useful to have an estimate on the amount of memory used by DOM structures. Using this data in the heap profiler in Web Inspector we can help web developers fix leaks in their applications. The heap profiler will be able to show that e.g. a particular JS wrapper is holding an XX megabyte DOM tree.

Looks good. It would also be nice to classify the memory usage to broad categories (strings, DOM, etc). You could make addSelfSize a template function so you could avoid repeating sizeof() everywhere.
