Bug 829248.  Implement basic support for [TreatUndefinedAs=Missing] in WebIDL.  r=khuey

This does not add support for [TreatUndefinedAs=Missing] in overloaded
methods, since it's not clear what that should really look like.

This also does not require that [TreatUndefinedAs=Missing] on an
argument force it on all later arguments, since it's not clear that we
want that long-term.
