Memory instruction widening recipes use the pointer operand of their load/store ingredient for generating the needed GEPs, making it difficult to feed these
recipes with pointers based on other ingredients or none at all.
This patch modifies these recipes to use a VPValue for the pointer instead, in order to reduce ingredient def-use usage by ILV as a step towards full VPlan-based def-use relations. The recipes are constructed with VPValues bound to these ingredients, maintaining current behavior.
