AST generation: fix handling of separation classes
In particular, make sure that the classes remain separate.
After removing the previous classes from the current class,
we would intersect the result with the schedule domain
and then eliminate inner dimensions. This elimination process
may drop some constraints that are needed to ensure that the
current class is disjoint from the previous classes.
We therefore intersect the result of the elimination step
with the current separation class domain.
