This was designed to be a test for https://bugs.webkit.org/show_bug.cgi?id=68944
But it seems that by far our dominating cost for the HTML5 benchmark is
time spent laying out lines (which isn't actually that surprising).
I'm adding the performance test for posterity.
* Parser/html-parser.html:
- Removed use of "about:blank" which abarth says is a no-op. Made comment more accurate.
* Parser/html5-full-render.html: Copied from PerformanceTests/Parser/html-parser.html.
