Adding handling for '-h' and '-v' options to invoke help and version
command respectively.
Current behaviour is:
$ perf -v
Unknown option: -v
Usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
$ perf -h
Unknown option: -h
Usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
New behaviour:
$ perf -h
usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
The most commonly used perf commands are:
annotate Read perf.data (created by perf record) and display annotated code
archive Create archive with object files with build-ids found in perf.data file
bench General framework for benchmark suites
...
$ perf -v
perf version 4.3.rc3.gc99e32
