  [PGO] Report number of counts being dropped when a hash-mismatch happens

This patch reports number of counts being dropped when a hash-mismatch
happens. This information will be helpful to the users -- if the dropped
counts are large, the user should redo the instrumentation build and
recollect the profile.
