Reviewed by Antti Koivisto.
Add performance tests for traversal of *uncached* collections returned
by getElementsByClassName() / getElementsByTagName(). These methods
will soon be updated to return an HTMLCollection instead of a
NodeList and we need to make sure we don't regress performance in the
process.
* DOM/get-elements-by-class-name-traversal-uncached.html: Added.
* DOM/get-elements-by-tag-name-traversal-uncached.html: Added.
