What is font-lock-mode-hook?

I can't see where it is defined or run.

Indeed, see:

It's defined (and run) as part of the `define-minor-mode' used for
font-lock-mode.

Ah, thanks. A bit puzzling though.

It's created automatically by define-minor-mode.

From font-core.el:

  (define-minor-mode font-lock-mode ...)

Then in easy-mode.el:

  (defmacro define-minor-mode (mode ...
    ...
    ; mode-name is (symbol-name mode)
    (hook (intern (concat mode-name "-hook")))
    (hook-on (intern (concat mode-name "-on-hook")))
    (hook-off (intern (concat mode-name "-off-hook")))

Anyway, this is documented pretty well (in the docstrings and the Elisp
manual), so please refer to that for more detail.

Thanks Jonathan, sorry for not observing this.

It would be nice if the actual hook variables doc strings had some 
explanation of this of course.

I am inclined to agree with you here.  I will take a look tonight and
see if I can easily add a bit of documentation to these auto-generated
variables.
