One of these records is kept for each identifier that is lexed.
This contains information about whether the token was #define'd, is a language keyword, or if it is a front-end token of some sort (e.g. a variable or function name). The preprocessor keeps this information in a set, and all tok::identifier tokens have a pointer to one of these.
