…ctionResult, nfc (#140245) When reducing unrolled parts, explicitly check for min/max reductions using the function RecurrenceDescriptor::isMinMaxRecurrenceKind. Only if the reduction is not min/max reduction, call RecurrenceDescriptor::getOpcode() to handle other cases via CreateBinOp. Based on #140242 Related to #118393
