Commit 73152a2ec20766ac45673a129bf1f5fc97ca9bbe fixed type checking for
blocks with qualified id parameters. But there are existing APIs in
Apple SDKs relying on the old type checking behavior. Specifically,
these are APIs using NSItemProviderCompletionHandler in
Foundation/NSItemProvider.h. To keep existing code working and to allow
developers to use affected APIs introduce a compatibility mode that
enables the previous type checking. This mode is enabled only on Darwin
platforms.
