Subject: [PATCH 01/13] perf tools: Fix the bash completion for listing options of perf subcommand

The bash completion does not support listing options for 'perf
kvm|kmem|mem|lock|sched --<TAB>', where 'kvm|kmem|mem|lock|sched' are
all subcommands of perf.

Example:

Before this patch:

 $ perf kvm --<TAB>
 $

As shown above, the options of perf kvm does not come out.

After this patch:

 $ perf kvm --<TAB>
 --alloc    --caller   --input    --line     --raw-ip   --sort
 --verbose

As shown above, the options of perf kvm can come out now.
