Change the syntax of availability queries from #available(iOS >= 8.0, OSX >= 10.10, *) to This change reflects the fact that now that we spell the query '#available()' rather than '#os()', the specification is about availability of the APIs introduced in a particular OS release rather than an explicit range of OS versions on which the developer expects the code to run. There is a Fix-It to remove '>=' to ease adopting the new syntax. Swift SVN r28025
