This set first adds smp_* barrier variants to tools infrastructure

see individual patches, thanks!

Arnaldo, if there are no objections, could this be routed via bpf-next
with Acked-by's due to later dependencies in libbpf? Alternatively,
I could also get the 2nd patch out during merge window, but perhaps
it's okay to do in one go as there shouldn't be much conflict in perf
itself.

Thanks!

v1 -> v2:
  - add common helper and switch to acquire/release variants
    when possible, thanks Peter!

Applied, Thanks
