Summary: Add check_clang_tidy.py script that is functionally identical to the check_clang_tidy.py, but should also be functional on windows. I've verified that the script works on linux. Would be nice if folks using Windows could test the patch before I break windows bots ;) Reviewers: chapuni, aaron.ballman Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D12180 llvm-svn: 245583
