Older GCC (<4.8) isn't smart enough to optimize !__builtin_constant_p() branch in bpf_htons. I recently fixed it for pkt_v4 and pkt_v6 in commita0517a0f7e
("selftests/bpf: use __bpf_constant_htons in test_prog.c"), but later added another bunch of bpf_htons in commitbf0f0fd939
("selftests/bpf: add simple BPF_PROG_TEST_RUN examples for flow dissector"). Fixes:bf0f0fd939
