a750893f - [VPlan][LV] Fix invalid truncation in VPScalarIVStepsRecipe (#137832)

[VPlan][LV] Fix invalid truncation in VPScalarIVStepsRecipe (#137832) Replace CreateTrunc with CreateSExtOrTrunc in VPScalarIVStepsRecipe to safely handle type conversion. This prevents assertion failures from invalid truncation when StartIdx0 has a smaller integer type than IntStepTy. The assertion was introduced by commit 783a846.
