[perf-test] Add a benchmark for querySelector()
https://bugs.webkit.org/show_bug.cgi?id=87742
Reviewed by Ryosuke Niwa.
Now I am optimizing querySelector() (bug 87625).
This patch adds a performance test for querySelector().
query-selector-first.html queries an element that appears
at the head of the document. On the other hand,
query-selector-last.html queries an element that appears
at the tail of the document.
Test results in my desktop:
