Namhyung Kim e5f2024cb9 perf ftrace profile: Add --graph-opts option 
Like trace subcommand, it should be able to pass some options to control
the tracing behavior for the function graph tracer.

But some options are limited in order to maintain the internal behavior.

For example, it can limit the function call depth like below:

  # perf ftrace profile --graph-opts depth=5 -- myprog

Committer testing:

  root@number:~# perf ftrace profile --graph-opts thresh=1000 -- sleep 1
  # Total (us)   Avg (us)   Max (us)      Count   Function
