RecipeListTy Recipes
The VPRecipes held in the order of output instructions to generate.

A special type of VPBasicBlock that wraps an existing IR basic block.

Recipes of the block get added before the first non-phi instruction in the wrapped block. Note: At the moment, VPIRBasicBlock can only be used to wrap VPlan's preheader block.
