I don't think I've ever actually successfully run the test-suite and
fully understood what I was doing. As you say, it is kind of a weird
relative to the LLVM project, but wouldn't moving it out of the
repository make it even more so? I wish it was instead more integrated
with the project, more useful, and better understood.

We branch, tag, and release test-suite as we do with the other modules
as part of the release process. That's maybe not super important for
most folks, but moving it to a separate repository would make that
process more complicated.

If the main motivation is 4), maybe we should consider moving the
whole repository to something that scales better?

Sorry if this is coming across as negative, but it just seems that the
most natural place for the LLVM test-suite is with the rest of LLVM,
so I don't see why we should move it without a good reason.
