For Swift 3 / 4: Deprecate the spelling "ImplicitlyUnwrappedOptional", emitting a warning and suggesting "!" in places where they are allowed according to SE-0054. In places where SE-0054 disallowed IUOs but we continued to accept them in previous compilers, emit a warning suggesting "Optional" or "?" as an alternative depending on context and treat the IUO as an Optional, noting this in the diagnostic. For Swift 5: Treat "ImplicitlyUnwrappedOptional" as an error, suggesting "!" in places where they are allowed by SE-0054. In places where SE-0054 disallowed IUOs, emit an error suggestion "Optional" or "?" as an alternative depending on context.
