88c5da047e Warm up RNG when --random_seed is used
The RNG state is initialized with random_seed parameter that usually
has lots of zeros. Each random generation iteration shuffles bits with
xor operation over the state. It takes a while before the state is populated
with enough 1s and starts generating uniformly distributed numbers.

The patch warms up the state with 32 iterations when --random_seed is used.
