Follow-up from apache#11970, to improve performance. In the initial implementation, the `analyzer->int_set` would compute the intersection of all scope-based constraints when entering the scope, even if they weren't actually used. This commit delays the call to `Intersect` until required, following the same behavior as `ConstIntBound`.
