I noticed a few timers found in ‘M-x list-timers’ were anonymous lambdas
that show up like this:

   *           0.5s            t #<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_9>

That’s not particularly helpful when trying to figure out what timers
are being run. I tracked down the two that I have configured to eldoc
and jit-lock. This gives them names that can be traced.

I'm okay with the change.  Another fix maybe more general would have
having more information in the subr name.  I think Alan is working on
this in bug#66750 but I suspect it will not go in for emacs 30.
