Introduce helper bpf_insn_is_indirect_target to check whether a BPF instruction is an indirect jump target. Since the verifier knows which instructions are indirect jump targets, add a new flag indirect_target to struct bpf_insn_aux_data to mark them. The verifier sets this flag when verifying an indirect jump target instruction, and the helper checks the flag to determine whether an instruction is an indirect jump target.
