// AST_PredefinedType nodes denote the various predefined types such

// node has a field (the value of this field is from the enum
// AST_PredefinedType::PredefinedType) which denotes the specific predefined
// type that this node represents. There is only one node in the entire
// AST which represents each predefined type, such as long etc.
