[PR 83178] Adjust scan-dump-times count of devirt-22.C

[Martin Jambor]

Hi,

IPA-CP does an extra devirtualization in devirt-22.C now because Honza's
profiling changes have caused an extra edge to be maybe_hot_p.  The scan
dump is guarded with scan-dump-times, I assume so that we are alerted to
any changes in behavior of the patch, like now.

I have looked at the behavior of IPA-CP and also reviewed the new
profile info, which seems better or at least not worse than before (more
info in my comment to the bug) and therefore I would like to propose to
adjust the test dump scan expected count in the patch below.

OK for trunk?

Thanks,

Martin
