Avoid loading cl-lib as result of invoking 'load-library'

Browse source 
* lisp/emacs-lisp/find-func.el (find-function--any-subform-p):
Don't use 'cl-destructuring-bind'.
(find-library--from-load-history): Don't use 'cl-loop'.
* lisp/thingatpt.el (thing-at-point): Don't use 'cl-loop'.  This
avoids loading cl-lib whenever thingatpt.el is loaded, for
example, as result of "M-x load-library".
