When Arun was working on this, I asked him to explore if it could make sense to reuse
the "-b, --branch-stack"  perf report option. Because after all, this feature is doing
about the same than "-b" except it's using callchains instead of full branch tracing.
But callchains are branches. Just a limited subset of all branches taken on excecution.
So you can probably reuse some interface and even ground code there.

What do you think?
