[LV] Interleaving should not exceed estimated loop trip count.

Description

[LV] Interleaving should not exceed estimated loop trip count.

Currently we may do iterleaving by more than estimated trip count
coming from the profile or computed maximum trip count. The solution is to
use "best known" trip count instead of exact one in interleaving analysis.
