My understanding (derived from the containing directory's name) is that this script is used for creating the official release tarballs to be published on `releases.llvm.org` or GitHub. Are there plans to publish snapshots?

Short of that it's just a "create tarball for a given git hash", which isn't really LLVM-specific. Packagers will often have their own preferred way of creating snapshots, e.g. in Open Build Service <https://openbuildservice.org/> I'd use a source service to create the snapshots automatically.

But that's not up to me. If @hans and @tstellar are fine with this, it's good to go.

Makes sense to me, after all the result should ideally be reproducible. (Prior to compression at least.)

+    fi
----------------
Seems like this duplicates 77-83, maybe remove those lines?
