- Add frontend and standard library build support for tvOS. - Add frontend support for watchOS. watchOS standard library builds are still disabled during SDK bring-up. To build for TVOS, specify --tvos to build-script. To build for watchOS, specify --watchos to build-script (not yet supported). This patch does not include turning on full tests for TVOS or watchOS, and will be included in a follow-up patch. Swift SVN r26278
