Warn on uses of deprecated APIs

Browse Source 
Emit a warning when the developer uses an API that has been marked deprecated with an
availability attribute. Following the Clang behavior, we will only warn if the API is
deprecated on all deployment targets. For example, if an API is deprecated as of
OS X 10.11 but the minimum deployment target is 10.10 then no warning will be emitted.
