perf top: Support --group-sort-idx to change the sort order
'perf report' supports the option --group-sort-idx, which sorts the output by the event at the index n in event group. For example: perf record -e cycles,instructions,cache-misses perf report --group --group-sort-idx 2 --stdio The perf-report output is sorted by cache-misses. This patch supports --group-sort-idx in perf-top. For example: perf top --group -e cycles,instructions,cache-misses --group-sort-idx 2 The perf-top output is sorted by cache-misses.
