[llvm-branch-commits] [llvm] [VPlan] Model address separately. (PR #72164)

[Florian Hahn via llvm-branch-commits]

Move vector pointer generation to a separate VPInstruction opcode.
This untangles address computation from the memory recipes future
and is also needed to enable explicit unrolling in VPlan.
