This change lets LLVM use the LC_BUILD_VERSION command when building for macOS 10.14, iOS 12, tvOS 12, and watchOS 5. Additionally, this change ensures that new platforms like Apple Silicon macOS / Mac Catalyst, and simulators running on Apple Silicon alway use LC_BUILD_VERSION with the OS version set to the minimum supported OS version if the deployment target version is older.
