remove the "variable 'ao2' inferred to have type 'AnyObject', which may be unexpected"
warning, in the case of an AnyObject or AnyObject? type.  Keep it around for ()
and AnyObject.Type.

The rationale for checking this has been reduced as the SDK is getting audited and
improved with generics, and it is problematic in the face of pattern matching, where
there isn't a simple pattern for silencing it.
