[issue25768] compileall functions do not document or test return values

[Brett Cannon]

Brett Cannon added the comment:

The patch LGTM, Nicholas! I'll commit it when I have a chance.

As for docs on test_importlib, nothing in the tests directory is documented to prevent people from depending on it since all the code in that directory is explicitly meant for testing Python and not general use.
