Enable checking for uses of potentially unavailable APIs. There is a frontend option to disable it: -disable-availability-checking. This commit updates the SDK overlays with @availability() annotations for the declarations where the overlay refers to potentially unavailable APIs. It also changes several tests that refer to potentially unavailable APIs to use either #available() or @availability annotations. Swift SVN r27272
