Commit 14e87ffa5c54 needlessly added support for CONSTR_NOTNULL entries to StoreConstraints. It's dead code, so remove it. To make the situation regarding constraint creation clearer, change comments in heap_create_with_catalog, StoreConstraints, MergeAttributes to explain which types of constraint are used on each.
