** This function looks up an identifier to determine if it is a
** keyword. If it is a keyword, the token code of that keyword is
** returned. If the input is not a keyword, TK_ID is returned.
**
** The implementation of this routine was generated by a program,
** mkkeywordhash.c, located in the tool subdirectory of the distribution.
** The output of the mkkeywordhash.c program was manually cut and pasted
** into this file. When the set of keywords for SQLite changes, you
** must modify the mkkeywordhash.c program (to add or remove keywords from
** the data tables) then rerun that program to regenerate this function.
