Wei Mi 7fb400112f [SampleFDO] Add a cutoff flag to control how many symbols will be included ...

into profile symbol list.

collected from production can cause unexpected performance behavior
in test. To triage such issue, it is useful to have a cutoff flag
to control how many symbols will be included into profile symbol list
in order to do binary search.
