Doug Gregor 4e0e32197f Extend 'availability' attribute with an unconditional 'deprecated' option. ...

Allow an unversioned 'deprecated' attribute to specify unconditional
deprecation of an API, e.g.,

  @availability(*, deprecated, message="sorry")
  func foo() { }

Also support platform-specific deprecation, e.g.,

  @availability(iOS, deprecated, message="don't use this on iOS")
  func bar() { }
