This patch modifies command-list.txt for the entry of
perf-bench. So perf will show 'bench' in command list.
Example:
% perf
usage: perf [--version] [--help] COMMAND [ARGS]
The most commonly used perf commands are:
annotate Read perf.data (created by perf record) and display annotated code
bench General framework for benchmark suites
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
list List all symbolic event types
probe Define new dynamic tracepoints
record Run a command and record its profile into perf.data
report Read perf.data (created by perf record) and display the profile
sched Tool to trace/measure scheduler properties (latencies)
stat Run a command and gather performance counter statistics
timechart Tool to visualize total system behavior during a workload
top System profiling tool.
trace Read perf.data (created by perf record) and display trace output
See 'perf help COMMAND' for more information on a specific command.

As suggested by Ingo, add a timechart man page help text, as well
as add it to the "perf help" overview.

This turn-key tool allows scheduler measurements to be
conducted and the results be displayed numerically.
First baby step towards that goal: clone the new command off of
perf trace.
Fix a few other details along the way:
- add (minimal) perf trace documentation
- reorder a few places
- list perf trace in the mainporcelain list as well
as it's a very useful utility.

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
