And for this one, having a hotkey to toggle children/no-children, in
'top', using a big hammer (perhaps the only one possible since we have
no perf.data file?) we could just trow away the existing hist_entries,
and flip the relevant flag, the new samples would then use the new mode,
etc.

For 'report' it would involve, at first sight, reprocessing everything,
possibly saving some work because we already did symbol resolution, etc,
i.e. the struct machine with its threads, etc will be all there.
