Issue Description:

The following code compiles on macOS, but fails to compile on Linux (Ubuntu 18.04 - Swift 5.1.1):

protocol Creatable {
    static func make() -> Self?
}

extension Optional: Creatable where Wrapped: Creatable {
    static func make() -> Self? {
        return Wrapped.make()
    }
}

The failure message:

Remangling failed:
