Replace A+Send trait subtyping with upcast coercion #23423

  1. Remove subtyping for object types and replace with an *upcast* coercion. 

    This upcast coercion currently preserves the vtable for the object, but
eventually it can be used to create a derived vtable. The upcast
coercion is not introduced into method dispatch; see comment on rust-lang#18737
for information about why. Fixes rust-lang#18737.
