bpf: Add loop test case with 32 bit reg comparison against 0
Add a loop test with 32 bit register against 0 immediate:
# ./test_verifier 631
#631/p taken loop with back jump to 1st insn, 2 OK
Disassembly:
[...]
1b: test %edi,%edi
1d: jne 0x0000000000000014
[...]
Pretty much similar to prior "taken loop with back jump to 1st
insn" test case just as jmp32 variant.
