Okay, I just bumped into r277008, in which commits to llvm, clang, and
clang-tools-extra all have the same SVN revision number.
I don't know how it happened but it did.  Is this just an artifact of
how somebody pasted together a bunch of git-svn projects, or is it
something that a top-level git repo with submodules would allow?
And if it is, then the "only thing a monorepo gets you" isn't
something
that you need a monorepo to get.
