Eric Fiselier 2373382284 Rewrite compare_bench.py argument parsing. ... This patch cleans up a number of issues with how compare_bench.py handled the command line arguments. * Use the 'argparse' python module instead of hand rolled parsing. This gives better usage messages. * Add diagnostics for certain --benchmark flags that cannot or should not be used with compare_bench.py (eg --benchmark_out_format=csv). * Don't override the user specified --benchmark_out flag if it's provided. In future I would like the user to be able to capture both benchmark output files, but this change is big enough for now. This fixes issue #313.		2016-11-18 15:42:02 -07:00
