perf: compare diff algorithms
8c912ee (teach --histogram to diff, 2011-07-12) claimed histogram diff
was faster than both Myers and patience.
We have since incorporated a performance testing framework, so add a
test that compares the various diff tasks performed in a real 'log -p'
workload. This does indeed show that histogram diff slightly beats
Myers, while patience is much slower than the others.
