selftests/bpf: Add tests for bpf_for_each
23cf4cf 
In this patch - 1) Add a new prog "for_each_helper" which tests the basic functionality of the bpf_for_each helper. 2) Add pyperf600_foreach and strobemeta_foreach to test the performance of using bpf_for_each instead of a for loop The results of pyperf600 and strobemeta are as follows: ~strobemeta~ Baseline verification time 6808200 usec stack depth 496 processed 592132 insns (limit 1000000) max_states_per_insn 14 total_states 16018 peak_states 13684 mark_read 3132 #188 verif_scale_strobemeta:OK (unrolled loop) Using bpf_for_each verification time 31589 usec stack depth 96+408 processed 1630 insns (limit 1000000) max_states_per_insn 4 total_states 107 peak_states 107 mark_read 60 #189 verif_scale_strobemeta_foreach:OK ~pyperf600~ Baseline verification time 29702486 usec stack depth 368 processed 626838 insns (limit 1000000) max_states_per_insn 7 total_states 30368 peak_states 30279 mark_read 748 #182 verif_scale_pyperf600:OK (unrolled loop) Using bpf_for_each verification time 148488 usec stack depth 320+40 processed 10518 insns (limit 1000000) max_states_per_insn 10 total_states 705 peak_states 517 mark_read 38 #183 verif_scale_pyperf600_foreach:OK Using the bpf_for_each helper led to approximately a 100% decrease in the verification time and in the number of instructions.
