Previously - it would silently run the perf suite w/o using

Everything in test-lib should be available - so yes! I can try it out
and switch to it in the next roll of this patch series. I did not
realize this helper was available. Thank you.

Allows for simple perf comparison of different integrations. I ran it
to compare our perl script w/ rs-git-fsmonitor and found 20-30ms of
overhead on every command.
Output looks like this (extra newlines added for readability)

This benchmark covers the git status time for a heavily
dirty directory - benchmarking fsmonitor's refresh
When running to compare our perl vs rs-git-fsmonitor - we see that
the perl script incurs significant overhead - further motivation
to provide a faster implementation within git.
