Subject: Treebuilder: Massively optimise element type from name with gperf.

Loading the html5 single page spec:

* We were spending 10.81% of total runtime in
  element_type_from_name. Now it takes 0.66%
  of total runtime.
* Total instruction fetch cost is reduced from
  5,660,475,511 to 4,523,112,517.
