[perf-test] Add a binding benchmark for getElementById() for an undefined id
https://bugs.webkit.org/show_bug.cgi?id=86812
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 document.getElementById() for an undefined id.
This benchmark covers 'getElementById (not in document)' in Dromaeo/dom-query.html,
and other Node-query methods that return a null.'
(Note: This benchmark is slower than document.getElementById() for a defined id.
We will fix the performance issue soon.)
