[LV] VPValues for memory operation pointers (NFCI)
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.
