+Use Unix style line endings for C/C++ source files (``.c``, ``.cpp`` and header
+files). This is required to avoid various build issue for downstream clients of
+LLVM. Test files like C/C++/HLSL test inputs can continue to use any line ending
+style.

I don't think this is true? Test files are only allowed to use CRLF line endings if those are required for the specific intent of the test (testing handling of CRLF, or the file format requires it).
