Ah, yes, that's a good idea, silence the warning so it won't trigger build failure on the bot which upgrades to error. I applied this to my local llvm-project clone and the build worked. I agree that this will never work on 10.13, and fine with it. 

If you want to reproduce yourself, you might want to clone llvm-project from Apple fork on Github: git at github.com:swiftlang/llvm-project.git
