Daniel Borkmann fa47a16b04 bpf: test case to check whether src/dst regs got mangled by xadd
We currently do not have such a test case in test_verifier selftests
but it's important to test under bpf_jit_enable=1 to make sure JIT
implementations do not mistakenly mess with src/dst reg for xadd/{w,dw}.
