perf report: Show branch info in callchain entry for browser mode 



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

If no iterations, the "iterations" is hidden.
