We would like to know whether a bpf_prog corresponds to the main prog or one of the subprogs. The current JIT implementations simply check this using the func_idx in bpf_prog->aux->func_idx. When the index is 0, it belongs to the main program, otherwise it corresponds to some subprogram.
This will also be necessary to halt exception propagation while walking the stack when an exception is thrown, so we add a simple helper function to check this, named bpf_is_subprog, and convert existing JIT implementations to also make use of it.
