Detailed Description
GNUNullExpr - Implements the GNU __null extension, which is a name for a null pointer constant that has integral type (e.g., int or long) and is the same size and alignment as a pointer. The __null extension is typically only used by system headers, which define NULL as __null in C++ rather than using 0 (which is an integer that may not match the size of a pointer).

SourceLocation tokens are not useful in isolation - they are low level value objects created/interpreted by SourceManager. We assume AST clients will have a pointer to the respective SourceManager.
