Now that I'm able to open the entire SDK in VSC, I'm fixing some of the analysis issues in various files (carefully) without changing their meaning. In this case, I removed unnecessary imports from benchmarks. In regexp_benchmark I ignored one warning which likely would have changed the behavior of the code.
