  Log Message:
  -----------
  [LV] Reverse mask up front, not when creating vector pointer. (#72163)

Reverse mask early on when populating BlockInMask. This will enable
separating mask management and address computation from the memory
recipes in the future and is also needed to enable explicit unrolling in
VPlan.
