It was an obsolete alias since Emacs 20.3 and was removed by this
commit:

commit 107f832577123ea7ebe867cba55601d0142f546f
Author: Stefan Kangas <stefan@marxist.se>
Date:   Sun Jul 31 11:33:42 2022 +0200

    Delete additional items obsolete since 20, 21 and 22
    
    * lisp/font-lock.el (font-lock-reference-face): Delete variable
    alias obsolete since 20.3.
    * lisp/progmodes/cc-cmds.el (c-toggle-auto-state): Delete alias
    obsolete since 22.1.
    * lisp/replace.el (query-replace-regexp-eval): Delete function
    obsolete since 22.1.
    (replace-count, replace-re-search-function): Doc fixes; adjust for
    above deleted function.

Code should use font-lock-constant-face instead.  I'm also confused
because I still see references to the old variable name in the Emacs
codebase.
