* Replace stdlib and test/stdlib 9999 availability. macOS 9999 -> macOS 10.15 iOS 9999 -> iOS 13 tvOS 9999 -> tvOS 13 watchOS 9999 -> watchOS 6 * Restore the pre-10.15 version of public init?(_: NSRange, in: __shared String) We need this to allow master to work on 10.14 systems (in particular, to allow PR testing to work correctly without disabling back-deployment tests).
