This patch introduces TripCount and RuntiVF as live-in VPValues whose underlying IR Values are available only at plan execution time. 
Canonical induction variable is cached so it can be reused when creating EVL recipe.

This patch is second in the series of patches to enable predicated vectorization support in LV introduced in RFC D99750 <https://reviews.llvm.org/D99750>.
