I agree with others that this discussion doesn't have to delay the
official repo from being posted.  Let's get that done ASAP.  Lots of
people are waiting on it.

SGTM.  I don't think we need a -final suffix or anything.  A straight
version number seems to convey intent for many other projects.  But not
a big deal either way.

We almost certainly want annotated tags.

I agree that -git or -dev could be misleading.  I also agree that we may
not need this tag at all.  If we want the tag, I thirdly agree that
tagging the split point is more useful/convenient than tagging the
version bump.

I have a preference for an llvm.org prefix on this tag, just like for
the release tags, for the same reason we have it there: namespacing to
avoid downstream conflicts.  But it's certainly not a dealbreaker.
