We should name this differently.  The NamedPropertyGetter/Setter and
IndexedPropertyGetter/Setter *are* the interceptors.  Returning an empty handle
from an interceptor signal to V8 that it should continue normal JavaScript
lookup on the actual JavaScript wrapper objects.  Call it something like
continueLookup?
