perf stat: Add branch performance metric

When we count both branches and branch-misses it is useful to
print out the percentage of branch-misses:

 # perf stat -e branches -e branch-misses /bin/true

 Performance counter stats for '/bin/true':

         401684  branches                 #      0.000 M/sec
          23301  branch-misses            #      5.801 %
