OPT_SET_INT was renamed to OPT_SET_UINT since the only use in these
tools is to set something that has an enum type, that is builtin
compatible with unsigned int.
Several string constifications were done to make OPT_STRING require a
const char * type.

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]

'perf bench mem memcpy' is a benchmark suite for measuring memcpy()
performance.
Example on a Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz:
| % perf bench mem memcpy -l 1GB
| # Running mem/memcpy benchmark...
| # Copying 1MB Bytes from 0xb7d98008 to 0xb7e99008 ...

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
