[perf-test] Add a benchmark for body.scrollTop
https://bugs.webkit.org/show_bug.cgi?id=86806
Reviewed by Ryosuke Niwa.
Currently Bindings/dom-attributes.html is just a collection of random
DOM attributes and methods. We should remove it and instead add more
reasonable micro benchmarks by classifying DOM binding call paths.
This patch adds a benchmark for body.scrollTop, which covers other
DOM attributes that return small integers.
(Note: Performance optimization for the benchmark will be coming soon.)
Test results in my Linux desktop:
