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.
