perf sched: Make common options cascading
The -i and -v options can be used in subcommands so enable cascading the
sched_options. This fixes the following inconvenience in 'perf sched':
$ perf sched -i perf.data.sched map
... (it works well) ...
$ perf sched map -i perf.data.sched
Error: unknown switch `i'
Usage: perf sched map [<options>]
--color-cpus <cpus>
highlight given CPUs in map
--color-pids <pids>
highlight given pids in map
--compact map output in compact mode
--cpus <cpus> display given CPUs in map
With this patch, the second command line works with the perf.data.sched
data file.
