Thanks @HaoyuZhang for adding the flag and the documentation. I just edited the
message a bit; otherwise looks good.

----------------
[OPTIONAL] Sampling-based profiles can have inaccuracies or missing block/edge
counters. The profile inference algorithm (profi) can be used to infer missing
block and edge counts and improve the quality of profile data. To apply the
optimization, add an extra flag ``-fsample-profile-use-profi`` to the command
line.
