The expected behavior is to have something similar than python:
https://docs.python.org/dev/library/argparse.html#dest:
"Any internal - characters will be converted to _ characters to make sure the string is a valid attribute name".
This allows to catch chromium arguments like 'isolated-script-test-output' that previously needed some preprocessing done for example in flags_compatibility.py.
This CL also fixes a fuchsia specific issue where the test runner needs a 'isolated-script-test-output' argument but then pass the argument to WebRTC that expects a 'isolated_script_test_output' argument. Thus calling flags_compatibility before the test_runner fails and there is not much room to change the argument in between the test runner and the test.
