Currently the presubmit script for 'git cl upload' will just warn the developer that code is incorrectly formatted and asks whether to proceed. This makes developers sometimes just ignore the warning and upload incorrectly formatted C++ code. This causes incorrectly formatted code to be committed to the repository and will cause a presubmit warning/question for all developers afterwards. This CL will therefore turn the warning into an error to ensure our c++ code is always correctly formatted. R=zra@google.com Review URL: https://codereview.chromium.org/2525633002 .
