Another thing that would be nice would be to automatically enable
these columns perf report when -b was enabled in the perf.data.
We can't check for timed LBR being supported without
looking into samples, but at least can check for -b.

Otherwise a lot of people won't realize it's supported.

It would show always 0.0 when timed LBR is not supported,
but that might be ok. Perhaps make both columns empty
in this case instead of 0.0.
