[perf-test] Add a binding benchmark for div.getAttribute()
https://bugs.webkit.org/show_bug.cgi?id=86814
Reviewed by Ryosuke Niwa.
We should remove Bindings/dom-attributes.html and instead add more
reasonable micro benchmarks by classifying DOM binding call paths.
This patch adds a benchmark for div.getAttribute(). This benchmark
covers 'getAttribute' in Dromaeo/dom-attr.html, and other DOM methods
that return a String.
Test results in my Linux desktop:
