I think we need to do the second one, ie, add it to
ConstraintAttributeSpec and do what's necessary to filter later.
The reason we have a problem here is exactly that somebody took
shortcuts.
It'd probably be sufficient to have one or two places in
parse_utilcmds.c know which variants of Constraint actually support
NOT VALID, and throw an error for the rest.
