These extensions were previously in `pkg/analyzer_utilities`, which is
not published on `pub`. That meant they could not be used from within
the `lib` directory of any package that *is* published on
`pub`. Specifically, they could not be used from within
`pkg/analyzer_testing/lib`.
In a follow-up CL, I will modify the testing logic so that after
printing `To accept the current state, expect:`, it prints diagnostic
codes in their proper camelCase format.
