Zhengjun Xing 2c8e64514a perf stat: Merge event counts from all hybrid PMUs ...

For hybrid events, by default stat aggregates and reports the event counts
per pmu.

  # ./perf stat -e cycles -a  sleep 1

   Performance counter stats for 'system wide':

      14,066,877,268      cpu_core/cycles/
       6,814,443,147      cpu_atom/cycles/

         1.002760625 seconds time elapsed

Sometimes, it's also useful to aggregate event counts from all PMUs.
Create a new option '--hybrid-merge' to enable that behavior and report
the counts without PMUs.

  # ./perf stat -e cycles -a --hybrid-merge  sleep 1

   Performance counter stats for 'system wide':

      20,732,982,512      cycles

         1.002776793 seconds time elapsed
