Add a bpf selftest benchmark that exercises bpf_kptr_xchg() in a tight loop
so helper vs inlined JIT paths can be compared on supported architectures.

Hi Chenguang,
Please send this generic selftest patch to the BPF mailing list.
It should be routed through the bpf-next tree.
Also, please use the '[PATCH bpf-next]' subject prefix to specify
that this is destined for the bpf-next tree.
For more info, please see:

Thanks,
Tiezhu
