Apple's own headers and tbd files prefer to think of Mac Catalyst as a distinct OS target. Earlier, when DriverKit support was added to LLVM, it was represented a distinct OS. So why Apple decided to only represent Mac Catalyst as an ABI in the target triple is beyond me. But this isn't the first time they've ignored established target triple norms (see: armv7k and aarch64_32) and it probably won't be the last. While doing this, I also audited all Darwin OS prongs throughout the codebase and made sure they cover all the tags.
