Yes! That's the final plan!
So, TableGen would generate two sets of files, one public and another
private. The former only containing high-level target descriptions,
cpu names, feature combinations, etc and the latter containing
everything else, from instructions to pipeline descriptions.
The public stuff should be available somewhere other projects can
access without having access to the other local files by accident.
Projects should not include them directly, but they'll include files
that include them, so the directory should be in the projects' paths,
too. We also may need to get these new classes into a library on its
