Hal Finkel 8c65549318 getSmallConstantTripMultiple should never return zero. ...

When the trip count is -1, getSmallConstantTripMultiple could return zero,
and this would cause runtime loop unrolling to assert. Instead of returning
zero, one is now returned (consistent with the existing overflow cases).
Fixes PR14167.
