f6884801 - [VPlan] Manage Sentinel value for FindLastIV in VPlan. (#142291)

[VPlan] Manage Sentinel value for FindLastIV in VPlan. (#142291) Similar to modeling the start value as operand, also model the sentinel value as operand explicitly. This makes all require information for code-gen available directly in VPlan. PR: https://github.com/llvm/llvm-project/pull/142291
