Research direction

Start with src/benchmarks/micro/runtime/Statements/If.cs at the linked AndAnd benchmark and run the supplied benchmarks_ci.py command using the IfStatements.IfStatements filter. Review the linked test report, history page, graph, and runtime comparison to determine whether the reported improvement needs follow-up; the issue does not define a code change or acceptance criteria.
