Subject: [PATCH] Adapt compilerplugins to llvm::sys::fs::OF_None rename

...from F_None, which happened with
<https://github.com/llvm/llvm-project/commit/1f67a3cba9b09636c56e2109d8a35ae96dc15782>
"[FileSystem] Split up the OpenFlags enumeration" towards LLVM 7, originally
leaving the alternative F_None spelling in for compatibility, but which was
finally removed now with
<https://github.com/llvm/llvm-project/commit/3302af9d4c39642bebe64dd60a3aa162fefc44b2>
"Support: Remove F_{None,Text,Append} compatibility synonyms, NFC".
