Detailed Description

VPRecipeBase is a base class modeling a sequence of one or more output IR instructions.

VPRecipeBase owns the the VPValues it defines through VPDef and is responsible for deleting its defined values. Single-value VPRecipeBases that also inherit from VPValue must make sure to inherit from VPRecipeBase before VPValue.
