I've made CSSStyleSelector::SelectorChecker::checkSelector() iterative to avoid stack overflow.
To achieve it, I have to maintain CallStack manually.

Hi reviewers,

I am afraid the code became unintuitive. But I guess it is inevitable. If you have any ideas to make it clean and intuitive, please let me know.

I also have a concern about performance. Is there any standard way to make sure a performance degradation won't happen by this change?


I'll fix CSSSelector:specifity() in another patch later. That might be an pretty easy task.
