Add a 'register-protocols' optimization that: Improves static registrar to: * Generate a new table of protocol -> managed wrapper type. This is required to find the wrapper type without having the `[Protocol]` attribute around. * Make the generated code implement protocols from [Adopts] attributes. This makes it possible to link away the `[Protocol]` attribute, because the native implementation of `conformsToProtocol:` does the right thing (we might even be able to link away our complete `ConformsToProtocol` logic when we remove the dynamic registrar). Improves linker to: * Not mark protocol interfaces by the mere virtue of having a type that implements them. This is implemented by not marking protocol interfaces when they're implementing a class, but instead when a method implementation is found to implement a method from a protocol interface. * Mark the wrapper type for protocols (this allows us to remove the Protocol attribute, since that's the link between the protocol and its wrapper type). * Remove the [Protocol], [ProtocolMember] and [Adopts] attributes (but only if optimizing protocols). The static registrar still needs some of the information linked away, so a few changes are required to make it available post linker.
