When declaring an ObjC interface decl with a @compatibility_alias alias name, change the class name to the "real" one. If we have something like @class NewImage; @compatibility_alias OldImage NewImage; @class OldImage; the lookup for 'OldImage' will return the 'NewImage' decl ("@class NewImage"). In such a case, when creating the decl for "@class OldImage" use the real declaration name ("NewImage"), instead of the alias one ("OldImage"), otherwise we will break IdentifierResolver and redecls-chain invariants.
