The test suite already works with index v5. Patch 5 and 6 fix the only cases where index-v5 would fail. To make it use index-v5 you can just set the INDEX_VERSION_DEFAULT to 5 in read-cache.c

I've never used it for performance testing yet, I'll try to run it with both versions and post the results. I don't think the results will be a lot different thought, since the test-suite usually uses small repositories.
