Joe Groff 962a87f444 SIL: Rename address-only existential instructions to '{init,deinit,open}_existential_addr'.
For better consistency with other address-only instruction variants, and to open the door to new exciting existential representations (such as a refcounted boxed representation for ErrorType).
