The branch info such as predicted/cycles/... are printed at the
callchain entries.
For example: perf report --branch-history --no-children --stdio
--1.07%--main div.c:39 (predicted:52.4% cycles:1 iterations:17)
main div.c:44 (predicted:52.4% cycles:1)
main div.c:42 (cycles:2)
compute_flag div.c:28 (cycles:2)
compute_flag div.c:27 (cycles:1)
rand rand.c:28 (cycles:1)
rand rand.c:28 (cycles:1)
__random random.c:298 (cycles:1)
__random random.c:297 (cycles:1)
__random random.c:295 (cycles:1)
__random random.c:295 (cycles:1)
__random random.c:295 (cycles:1)
But the current code is difficult to maintain and extend. This patch
refactors the code for easy maintenance.
Change log:
v6: 1. Put the multiline condition code into {} brackets in
counts_str_build()
2. Keep the original display order, that is:
predicted, abort, cycles, iterations
v5: It's a new patch in v5 patch series.

[ Don't use 'index' as a name for a variable, it shadows a globa decl in older distros ]
