This patch makes output of perf bench more friendly.
Current style of putput, keeping user wait
and printing everything suddenly when we finish,
may confuse users.
So I improved it:
| % perf bench sched messaging
| # Running sched/messaging benchmark... <- printed right after invocation
| # 20 sender and receiver processes per group
| # 10 groups == 400 processes run
|
| Total time: 1.476 [sec]

This patch modifies builtin-bench.c for processing common
options. The first option added is "--format".
Users of perf bench will be able to specify output style by
--format.
Usage example:
% ./perf bench sched messaging # with no style specify
(20 sender and receiver processes per group)
(10 groups == 400 processes run)
Total time:1.431 sec
% ./perf bench --format=simple sched messaging # specified
simple 1.431
