An eBPF JIT may implement JMP32 operations in a different way than JMP,
especially on 32-bit architectures. This patch adds a series of tests
for JMP32 operations, mainly for testing JITs.

Maybe change the offset from 1 to 2? Otherwise, this may jump to
   BPF_JMP32_REG(BPF_JGT, R0, R1, 1)
which will just do the same comparison and jump to BTT_EXIT_INSN()
which will also have R0 = 0xfffffffe at the end.

ditto, change offset 1 to 2?

You are right. All BPF_X versions should have the first jump offset
incremented by one to account for the extra MOV that is not present in
the BPF_K version of the test. I'll correct it.
