perf bench: Add "all" pseudo subsystem and "all" pseudo suite
This patch adds a new "all" pseudo subsystem and an "all" pseudo
suite. These are for testing all subsystem and its all suite, or
all suite of one subsystem.
(This patch also contains a few trivial comment fixes for
bench/* and output style fixes. I judged that there are no
necessity to make them into individual patch.)
Example of use:
| % ./perf bench sched all # Test all suites of sched subsystem
| # Running sched/messaging benchmark...
| # 20 sender and receiver processes per group
| # 10 groups == 400 processes run
|
| Total time: 0.414 [sec]
|
| # Running sched/pipe benchmark...
| # Extecuted 1000000 pipe operations between two tasks
|
| Total time: 10.999 [sec]
|
| 10.999317 usecs/op
| 90914 ops/sec
|
| % ./perf bench all # Test all suites of all subsystems
| # Running sched/messaging benchmark...
