Andi Kleen 508be0dfe6 perf report: Add srcline_from/to branch sort keys 
Add "srcline_from" and "srcline_to" branch sort keys that allow to show
the source lines of a branch.

That makes it much easier to track down where particular branches happen
in the program, for example to examine branch mispredictions, or to
associate it with cycle counts:

  % perf record -b -e cycles:p ./tcall
  % perf report --sort srcline_from,srcline_to,mispredict
  ...
    15.10%  tcall.c:18       tcall.c:10       N
