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 %
