These queries are currently run by default, but don't have their results displayed.
Looking through results on LGTM.com, they are either false positives (e.g., `BitwiseSignCheck` which flags many perfectly harmless operations and `CompareIdenticalValues` which mostly flags NaN checks) or harmless results that developers are unlikely to care about (e.g., `EmptyArrayInit` or `MisspelledIdentifier`).
With this PR, the only queries that are still run but not displayed are security queries, where different considerations may apply.
