Evgeniy Brevnov af7e158872 [LV] Vectorizer should adjust trip count in profile information
Summary: Vectorized loop processes VFxUF number of elements in one iteration thus total number of iterations decreases proportionally. In addition epilog loop may not have more than VFxUF - 1 iterations. This patch updates profile information accordingly.
