If `--driver-mode` is passed in one or more times, it will overwrite the default by this patch.  This patch only makes it so that if NO `--driver-mode` is passed in, we try to do better than saying "must be GCC".

This is one of two steps necessary to get clang-tidy working on Windows.  However, despite that, this change seems correct even in the general sense.  If a `--driver-mode` option is not passed in, we should make the most informed possible decision we can.
