Note that at this point we actaully do Xrays for all of our various
property types, except in worker code. The real substantive change
here is the change to what usedForXrays returns. The rest is minor
cleanup.
Switch from using the interface objects from the Xrays compartment to wrapping
interface objects and interface prototype objects in Xrays. Make dom binding
Xrays deal with both instance objects and interface and interface prototype
objects.
Pass two objects when creating a DOM interface object, the global used to cache
the DOM interface objects and a receiver object on which the named property is
that points to the DOM interface object.
