Nothing would need to be rewritten in Python to publish as a pip package. The plan was to ship the existing binaries.

I guess for `split-file` we could feasibly reimplement it as a lit builtin, but if we're already going to be shipping FileCheck which I don't think we want to put the effort in to reimplement, we shouldn't reimplement `split-file` given the effort of shipping both is probably 5% more than shipping one.
