Namhyung Kim 414e050c68 perf sched timehist: Add --state option
The --state option is to show task state when switched out.  The state
is printed as a single character like in the /proc but I added 'I' for
idle state rather than 'R'.

  $ perf sched timehist --state | head
  Samples do not have callchains.
