But it's no buffer-local variable, it's a function.  If you have emacs
25.1 upwards, you have `font-lock-ensure'.

I think that's a common check for 3rd-party packages which want to keep
supporting emacs 24.  But since you are hacking emacs core, there's no
need for that unless the function/variable is only defined if some
configure option is given or some lib is available.  But none of the
latter applies to font-lock.el.
