While I like a lot about this design, I'd like to also have a common
location for a common set of these "modules" so that it is really easy for
all of us to test the same stuff and talk about the same test failures. =]

It also isn't the design we have today, and I'd rather not wait on it to

But if we ever do get here, none of my arguments above about why we should
do this really apply to an isolated chunk of infrastructure. I'd be happy
for that to live in LLVM's main repo, or anywhere else really. I'm mostly
talking about the common collection of actual test suite stuff.
