Add a test for the -G and -S pickaxe options and related options. This test supports being run with GIT_PERF_EXTRA=1 to turn on the full set of tests, as well as GIT_TEST_LONG=1 to opt-in a full history walk. By default I'm limiting the walk to 500 commits, which seems to hit a good spot on git.git of around 0.5s per iteration.
