[PATCH v2 5/6] perf report: Show branch info in callchain entry for browser mode

[Jin Yao]

If the branch is 100% predicated then the "predicated" is hide.
Similarly, if there is no branch tsx abort, the "abort" is hide.
There is only cycles shown (cycle is supported on skylake platform,
older platform would be 0).
