@objc enums have special requirements on the raw type, which were enforced as part of checking the raw type of the enum. Rework the checking here so that the additional constraints are part of resolving whether the enum is exposed to Objective-C. This keeps raw-type computation more independent and “lower-level” than @objc computation. Once reworked, eliminate the “CIntegerTypes” cache from TypeChecker: it probably doesn't matter, and the caching should be performed by the request-evaluator rather than the type checker.
