[PATCH 10/10] perf stat: Support inherit/no-inherit terms

[Jiri Olsa]

Adding support to use 'inherit' and 'no-inherit' terms
in perf stat command, like:

To disable perf_event_attr::inherit (enabled by default):

  $ perf stat -e cpu/cpu-cycles,no-inherit/u ...

Enable perf_event_attr::inherit (disabled by -i):

  $ perf stat -i -e cpu/cpu-cycles,inherit/u ...
