Previous patch has implemented a new sort option "total_cycles".
But there was only stdio mode supported.
This patch supports the tui mode and support '--percent-limit'.
For example,
perf record -b ./div
perf report -s total_cycles --percent-limit 1

Minor change since the function name is changed:
block_total_cycles_percent -> block_info__total_cycles_percent

That will be a little bit complicated. But OK, I will try that.
Thanks
