I think deleting the FIXME is fine.

If one were going to do that, one would indicate whether they applied
by splitting TYPE_CODE_ARRAY into TYPE_CODE_ARRAY and
TYPE_CODE_FORTRAN_ARRAY, or something --- that is, let the
discriminant say which fields are present / meaningful.  But we don't
really do that, so it's not worth it.

Yes, please do.
