Currently we produce 'partial dills' for the VM when compiling through kernel, i.e. we only include the user-code and whatever canonical names the user refers to. That's perfectly fine for the VM as it always loads the platform.dill file too. We cannot currently print it though. (Technically we should be able to concatenate it with platform.dill and print that). This CL allows us to print these partial dills without concatenating anything first.
