…ints

Constraint.allows_any() only returned True for the '!=' operator when the other argument was a MultiConstraint or UnionConstraint. This caused incorrect False results for 'in' and 'not in' operators.

For MultiConstraint (AND): check that self is compatible with each individual constraint via all(self.allows_any(c) ...).

For UnionConstraint (OR): check if self overlaps any member via any(self.allows_any(c) ...).
