I want to figure out the meaning of --flags-histogram,but cannot get it from the source code.

It is for debugging/analysis. It prints out the top 20 flags most commonly used in the final (best) configurations over past training runs. So if you train a single program say 30 times, you can figure out which flags occur most commonly in the winning config.
