David Benjamin 7a62ab1938 Clarify BN_prime_checks is only for random candidates.
The relevant result (Damgård, Landrock, and Pomerance, Average Case
Error Estimates for the Strong Probably Prime Test) is only applicable
for randomly selected candidates. It relies on there being very few odd
composites with many false witnesses.

(If testing an adversarially-selected composite, false witnesses are
bounded by ϕ(n)/4 for n != 9, so one needs about 40 iterations for a
2^-80 false positive rate.)
