[PATCH] D102459: [clang][ObjC] Allow different availability annotation on a method when implementing an optional protocol requirement

[Alex Lorenz via Phabricator via cfe-commits]

Do not apply this to 'deprecated' availability annotations - the user has no way to check for deprecated as `respondsToSelector` will still return true even if the class has marked the method as deprecated.
