A self map (e.g., `map(self: x)`) by itself doesn't require unified shared memory. However, a `requires self_maps` directive does imply the `unified_shared_memory` requirement according to the spec. I suppose we could have said that USM is not implied and make them orthogonal properties, but that's not the direction we ended up taking with the requirement.
