Hey, thanks for contributing!

I usually look at the tests before looking at the actual change. Could you demonstrate the improvement?
You can grep for files containing similar diagnostics under the `clang/test/Analysis` folder if you look for the report messages. Pick one file which seems relevant to add your tests to.
