Fix division by zero in ipa-cp.cc:update_profiling_info

This ICE has triggered for me during autoprofiledbootstrap.  The
code already takes into care possible range, so I think in this case
we can just push to one side of it.

Bootstrapped/regtesed x86_64-linux, OK?

gcc/ChangeLog:

* ipa-cp.cc (update_profiling_info): Watch for division by zero.
