[PATCH v4 5/6] perf report: Show branch info in callchain entry for browser mode

From: Jin Yao
Date: Sun Oct 30 2016 - 21:19:43 EST


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).

If no iterations, the "iterations" is hide.
