Activate with `--config-impact-analysis`.

Supported languages:
- C/C++/ObjC: Experimental
- C#/.Net: Experimental

This checker collects functions whose execution isn't gated by certain pre-defined gating functions. The set of gating functions is hardcoded and empty by default for now, so to use this checker, please modify the code directly in [FbGKInteraction.ml](https://github.com/facebook/infer/tree/master/infer/src/opensource).
