More than half the commits are llvm's. (llvm-only mirror repo 175k,
llvm super-repo 310k)
So it adds to the clone, but not that much.

The point is something else:
- llvm-mirror is not an official repo, and may become stale/unmaintained
- llvm-mirror does not have version tags, so we can't trace commit ids
to the releases, or track upstream development with automatic tools

I think these two things outweigh the extra clone overhead.

What I mean is there is no mention whatsoever that the recipe is
currently building a pre-release. It's not in PV, it's not anywhere in
the recipe. This can mislead people.
