Values produced by address-only `enum` instructions have non-none ownership. And because `enum` is representation-changing, they have `owned` ownership. This corresponds at the opaque values SIL stage to the fact that at the address-lowered SIL stage the storage location has non-trivial initialization which must be `destroy_addr`d, regardless of whether an empty case was stored to it.
