[PATCH] D19487: [LV] Reallow interleaved load groups with gaps

Addressed Silviu's comments.

Silviu, I think this revision addresses both of your comments about the peeling. I now only peel if TC % Step is zero. If the mod is zero, we know that TC >= Step, so the subtraction should not overflow. And we also know that there wouldn't already be scalar iterations due to Step not evenly dividing TC. Thanks for the feedback!
