HTML5 TreeBuilder regressed a Peacekeeper DOM test by 40%
https://bugs.webkit.org/show_bug.cgi?id=48719
It's unclear exactly what the Peacekeeper benchmark is testing,
because I haven't found a way to run it myself.
However, I constructed a benchmark which shows at least one possible slow point.
The HTML5 spec talks about creating a new document for every time we use
the fragment parsing algorithm. Document() it turns out, it a huge bloated
mess, and the constructor and destructor do a huge amount of work.
* benchmarks/parser/tiny-innerHTML.html: Added.
