[Performance test] Add a micro benchmark for div.firstChild getter
https://bugs.webkit.org/show_bug.cgi?id=86582
Reviewed by Ryosuke Niwa.
We are going to remove Bindings/dom-attributes.html and instead add more
reasonable micro benchmarks by classifying DOM binding call paths.
In this bug, we add a micro benchmark for div.firstChild getter.
This benchmark covers 'firstChild', 'lastChild', 'nextSibling' and
'previousSibling' in Dromaeo/dom-traverse.html, and other DOM attributes
that return a Node object.
Multiple test results in my Linux desktop:
