The values of NullableAnnotation are not in the order that they appear in the lattice. Please reorder them so that they are in lattice order; that would permit a much simpler implementation of Meet and Join.

The NullableAnnotation enum values are currently used as is in [NullableAttribute(values)] attributes in metadata, so changing the enum will be a breaking change unless we map to/from the current values when writing/reading metadata.
