    Original change's description:
    > [serializer] Change deferring to use forward refs
    > 
    > Now that we have forward references, we can replace the body deferring
    > mechanism with forward references to the entire pointer.
    > 
    > This ensures that objects are always deserialized with their contents
    > (aside from themselves maybe holding forward refs), and as a result we
    > can simplify the CanBeDeferred conditions which encode the constraint
    > that some objects either need immediately have contents, or cannot be
    > deferred because their fields are changed temporarily (e.g. backing
    > store refs).
    > 
    > This also means that objects with length fields (e.g. arrays) will
    > always have those length fields deserialized when the object is
    > deserialized, which was not the case when the body could be deferred.
    > This helps us in the plan to make GC possible during deserialization.
