Namhyung Kim edc41a1099 perf record: Enable off-cpu analysis with BPF 
Add --off-cpu option to enable the off-cpu profiling with BPF.  It'd
use a bpf_output event and rename it to "offcpu-time".  Samples will
be synthesized at the end of the record session using data from a BPF
map which contains the aggregated off-cpu time at context switches.
So it needs root privilege to get the off-cpu profiling.

Each sample will have a separate user stacktrace so it will skip
kernel threads.  The sample ip will be set from the stacktrace and
other sample data will be updated accordingly.  Currently it only
handles some basic sample types.

The sample timestamp is set to a dummy value just not to bother with
other events during the sorting.  So it has a very big initial value
and increase it on processing each samples.

Good thing is that it can be used together with regular profiling like
cpu cycles.  If you don't want to that, you can use a dummy event to
enable off-cpu profiling only.

Example output:
  $ sudo perf record --off-cpu perf bench sched messaging -l 1000

  $ sudo perf report --stdio --call-graph=no
  # Total Lost Samples: 0
  #
  # Samples: 41K of event 'cycles'
  # Event count (approx.): 42137343851
  ...

  # Samples: 1K of event 'offcpu-time'
  # Event count (approx.): 587990831640
  #
  # Children      Self  Command          Shared Object       Symbol
  # ........  ........  ...............  ..................  .........................
  #
      81.66%     0.00%  sched-messaging  libc-2.33.so        [.] __libc_start_main
      81.66%     0.00%  sched-messaging  perf                [.] cmd_bench
      81.66%     0.00%  sched-messaging  perf                [.] main

      81.43%     0.00%  sched-messaging  perf                [.] bench_sched_messaging
      40.86%    40.86%  sched-messaging  libpthread-2.33.so  [.] __read
      37.66%    37.66%  sched-messaging  libpthread-2.33.so  [.] __write
       2.91%     2.91%  sched-messaging  libc-2.33.so        [.] __poll
  ...

As you can see it spent most of off-cpu time in read and write in
bench_sched_messaging().  The --call-graph=no was added just to make
the output concise here.

It uses perf hooks facility to control BPF program during the record
session rather than adding new BPF/off-cpu specific calls.
