A dynamically typed AST node container.
Stores an AST node in a type safe way. This allows writing code that works with different kinds of AST nodes, despite the fact that they don't have a common base class.
Use create(Node) to create a DynTypedNode from an AST node, and get<T>() to retrieve the node as type T if the types match.
See ASTNodeKind for which node base types are currently supported; You can create DynTypedNodes for all nodes in the inheritance hierarchy of the supported base types.

Retrieve the stored node as type T.
Returns NULL if the stored node does not have a type that is convertible to T.
For types that have identity via their pointer in the AST (like Stmt, Decl, Type and NestedNameSpecifier) the returned pointer points to the referenced AST node. For other types (like QualType) the value is stored directly in the DynTypedNode, and the returned pointer points at the storage inside DynTypedNode. For those nodes, do not use the pointer outside the scope of the DynTypedNode.

Returns a pointer that identifies the stored AST node.
Note that this is not supported by all AST nodes. For AST nodes that don't have a pointer-defined identity inside the AST, this method returns NULL.

Retrieve the stored node as type T.
Similar to get(), but asserts that the type is what we are expecting.

Imposes an order on DynTypedNode.
Supports comparison of nodes that support memoization. FIXME: Implement comparsion for other node types (currently only Stmt, Decl, Type and NestedNameSpecifier return memoization data).
