Some of them are likely overkill, especially now that the analysis map is a separate optional entry rather than embedded in the function addr map.

I've reduced it to the *-pgo-features.ll which is the primary test and *-empty-function.ll to validate that the analysis map won't exist when bb addr map does not.
