For some platforms, for example Broadwell, it doesn't support cycles
for LBR. But the perf always prints cycles:0, it's not necessary.
The patch refactors the LBR info print code and drops the cycles:0.
For example: perf report --branch-history --no-children --stdio
On Broadwell:
--0.91%--__random_r random_r.c:394 (iterations:2)
__random_r random_r.c:360 (predicted:0.0%)
__random_r random_r.c:380 (predicted:0.0%)
__random_r random_r.c:357
On Skylake:
--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)

For some platforms, for example Broadwell, it doesn't support cycles
for LBR. But the perf always prints cycles:0, it's not necessary.
The patch refactors the LBR info print code and drops the cycles:0.
For example: perf report --branch-history --no-children --stdio
On Broadwell:

main div.c:44 (predicted:52.4% cycles:1)
