- Cache predicates in the same stage using a cached module. - Introduce `DefUse::defUseVariableUpdate()` and use in `CallableReturns.qll`. The updated file `csharp/ql/test/library-tests/cil/dataflow/Nullness.expected` demonstrates why this is needed. - Utilize CIL analysis in `Guards::nonNullValue()`. - Analyze SSA definitions in `AlwaysNullExpr`, similar to `NonNullExpr`.
