Fast verification pass -- the controls and the prediction rule, nothing slow.

reproduce.py runs the full set in about 16 minutes, dominated by rc5_64.py
sweeping to N=800,000. This runs the parts a reviewer wants first: does the
statistic behave on random data, is the signal carry-driven where claimed, and
does the rule predict.
