Add performance tests for NodeList and HTMLCollection traversal
https://bugs.webkit.org/show_bug.cgi?id=148043
Reviewed by Gavin Barraclough.
Add performance tests for NodeList and HTMLCollection traversal.
Ideally, those 2 tests should be as fast. However, due to inefficiencies
in our HTMLCollection bindings code, the HTMLCollection tests is ~30%
slower. This will be addressed in the near future.
* Bindings/childNodes-traversal.html: Added.
* Bindings/children-traversal.html: Added.
