Detailed Description

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. It is aligned to 8 bytes because DeclarationName needs the lower 3 bits.
