Parts of Webapi.Dom and the whole Js_typed_array module are removed here. Don't we want to keep these for compatibility?

I think it was discussed at the retreat that nobody uses js typed arrays. In fact, js array was also removed, but that seems more at risk of being used even if the bindings are old style.
The webapi stuff are just part of print tests, as part of larger files, and don't exercise any specific cases.
