xz is a data compression tool, so it's natural to have compressed files for (de)compression tests.
these files are also useful to check that the library we just built works correctly. but they aren't necessary for installation.
we may have more sophisticated procedures that will allow us to use some parts of distribution only for tests. This may significantly reduce an attack vector - many projects have huge, sophisticated testing infrastructure where you can hide the entire Wikipedia.
