[LV] Move code to place pointer induction increment to VPlan post-processing.
This patch moves the code to set the correct incoming block for the
backedge value to VPlan::execute.
When generating the phi node, the backedge value is temporarily added
using the pre-header as incoming block. The invalid phi node will be
fixed up during VPlan::execute after main VPlan code generation.
At the same time, the backedge value is also moved to the latch.
This change removes the requirement to create the latch block up-front
for VPWidenInductionPHIRecipe::execute, which in turn will enable
modeling the pre-header in VPlan.
Depends on D121617.
