Jin Yao 3fa7ae3f37 perf report: Fix wrong LBR block sorting 
[ Upstream commit f2013278ae40b89cc27916366c407ce5261815ef ]

When '--total-cycles' is specified, it supports sorting for all blocks
by 'Sampled Cycles%'. This is useful to concentrate on the globally
hottest blocks.

'Sampled Cycles%' - block sampled cycles aggregation / total sampled cycles

But in current code, it doesn't use the cycles aggregation. Part of
'cycles' counting is possibly dropped for some overlap jumps. But for
identifying the hot block, we always need the full cycles.

  # perf record -b ./triad_loop
  # perf report --total-cycles --stdio

Now the hottest block is reported at the top of output.
