[PATCH] D72841: Add support for pragma float_control, to control precision and exception behavior at the source level

Hi @rjmccall, I am also seeing similar failures. 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

but I don't know if this is the most correct approach.
