The progs for bpf selftests use several different notations to force
function inlining. Standardize to what most of them use,
static __always_inline.

selftests/bpf: add few verifier scale tests2019-04-03T23:27:38ZAlexei Starovoitovast@kernel.org2019-04-02T04:27:48Zurn:sha1:e5e7a8f2d858a91b79c4afc51a3f15edcbf9cb60
Add 3 basic tests that stress verifier scalability.
test_verif_scale1.c calls non-inlined jhash() function 90 times on
different position in the packet.
This test simulates network packet parsing.
jhash function is ~140 instructions and main program is ~1200 insns.
test_verif_scale2.c force inlines jhash() function 90 times.
This program is ~15k instructions long.
test_verif_scale3.c calls non-inlined jhash() function 90 times on
But this time jhash has to process 32-bytes from the packet
instead of 14-bytes in tests 1 and 2.
jhash function is ~230 insns and main program is ~1200 insns.
$ test_progs -s
can be used to see verifier stats.
