Detailed Description
A specialization of VPInstruction augmenting it with a dedicated result type, to be used when the opcode and operands of the VPInstruction don't directly determine the result type.
Note that there is no separate VPDef ID for VPInstructionWithType; it shares the same ID as VPInstruction and is distinguished purely by the opcode.
