[VPlan] Model FOR resume value extraction in VPlan. (llvm#93396)
This patch uses the ExtractFromEnd VPInstruction opcode to extract the value of a FOR to be used as resume value for the ph in the scalar loop. It adds a new live-out that temporarily wraps the FOR phi in the scalar loop. fixFixedOrderRecurrence will process live outs for fixed order recurrence phis by creating a new phi node in the scalar preheader, using the generated value for the live-out as incoming value from the middle block and the original start value as incoming value for the other edge. Creation of the phi in the preheader, as well as updating the phi in the scalar loop will also be moved to VPlan in the future, eventually retiring fixFixedOrderRecurrence Depends on llvm#93395 PR: llvm#93396
