Comment (by osa1):

 > When the ghc root directory is not a git repository, skip all
 performance tests.

 Is this really what we want? It doesn't make sense to me to skip
 performance tests simply because we're not in a git repo, as it doesn't
 indicate that I'm not interested in performance tests.

 Why not just skip recording perf numbers when not in a git repo instead?
