When we store the entire object, `enclosing_type' is the run-time

If `type' is a pointer to an object, then `enclosing_type' is a
pointer to the object's run-time type, and `pointed_to_offset' is
- the offset in bytes from the full object to the pointed-to object
- -- that is, the value `embedded_offset' would have if we followed

If we're not doing anything fancy, `enclosing_type' is equal to
`type', and `embedded_offset' is zero, so everything works
