So this is a quick summary of the problem we're facing: 
On SystemZ, we can accept both OF_Text or OF_TextWithCRLF, it makes no difference. However, there are many text files that are marked as binary/OF_None to suppress CRLF translation on Windows. (e.g. patches like this one https://reviews.llvm.org/rGe78a7a0ecddc747129512fabf4836e22d1805f00). On SystemZ we need the text files to be marked as text and have made patches in the past to do so (e.g. https://reviews.llvm.org/D67696). These efforts are conflicting with each other, so Reid suggested this solution where we create a new flag that will set text mode and turn on CRLF translation on Windows platform. Then we will be able to mark all remaining text files with OF_Text and not turn on CRLF translation for Windows.

I agree this patch is touching a lot of files,  I can maybe do the opposite and create a flag called OF_TextWithoutCRLF. I'm open to any new solutions to this problem.
