Good intermediate refactoring of VPWidenMemoryInstructionRecipe!

Perhaps better to peel off a single GEP-for-consecutive-memory Recipe rather than two VPInstructions, as first step?

May be good to eventually have separate recipes/VPInstructions for load, stores, gathers, scatters, possibly in some hierarchy to share common parts.
