bbc8fcb0 - [VPlan] Fix assertion when VPReductionPHIRecipe is simplified (#201023)

[VPlan] Fix assertion when VPReductionPHIRecipe is simplified (#201023) When replacing an invariant store of a reduction, we assert that the stored value is the backedge value. However in some cases the VPReductionPHIRecipe may be simplified away completely, so account for this. Fixes #201020 Fixes #200742
