class | IdentifierTable |
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.

Revert TokenID to tok::identifier; used for GNU libstdc++ 4.2 compatibility.
TokenID is normally read-only but there are 2 instances where we revert it to tok::identifier for libstdc++ 4.2. Keep track of when this happens using this method so we can inform serialization about it.
