It is failing on apple's master (and the swift branches as well) because ParseLangArgs and ParseCodeGenArgs are getting called in the opposite order in apple/master from the order they are called in llvm/master. I posted a PR to fix those failures here: https://github.com/apple/llvm-project/pull/1202

Oh, thank you for figuring that out.  Yeah, it's reasonable for code-gen option parsing to depend on language-option parsing, which means that this patch is wrong.  The right fix is that we need to stop parsing these as code-gen options, which is reasonable since they have direct language-semantics impact.  If we still need the code-gen option flags, we should be able to recreate them from the language options, I think.
