When the compiler encounters a method call, it performs a lookup using the type of the argument in the self position and the name of the method. If that type is TypeInfo::Unknown, there will be no methods to be found, because there are no methods implemented for the unknown type. To that end, we should probably have the compiler return an ICE in the case of a method lookup on an unknown type.
