Log Message
Add a version of the html-parser benchmark which uses srcdoc instead of document.write so it tests the threaded parser
https://bugs.webkit.org/show_bug.cgi?id=107158
Reviewed by Ryosuke Niwa.
Currently this test even opts-in to the threaded parser if available.
We'll remove that line when the threaded parser becomes default or goes away.
* Parser/html-parser-srcdoc.html: Added.
