Added recursive results to perf.py
This adds -P/--propagate and -Z/--depth to perf.py for showing recursive results, making it easy to narrow down on where spikes in performance come from. This ended up being a bit different from stack.py's recursive results, as we end up with different (diminishing) numbers as we descend.
