Remove specific byte-compiler warnings for cl.el

* lisp/emacs-lisp/bytecomp.el (byte-compile-warning-types)
(byte-compile-warnings, byte-compile-cl-file-p)
(byte-compile-eval, byte-compile-eval-before-compile)
(byte-compile-arglist-warn, byte-compile-find-cl-functions)
(byte-compile-cl-warn, displaying-byte-compile-warnings)
(byte-compile-file-form-require, byte-compile-form): Remove all
specific cl.el warnings, as that library is now obsolete.  The
regular obsoletion warnings are sufficiently discouraging.
* lisp/emacs-lisp/advice.el (ad-compile-function): Don't try to
silence the now removed warning.
* doc/lispref/tips.texi (Coding Conventions):
* doc/misc/cl.texi (Organization): Make recommendation to not use
cl.el and cl-compat.el stronger.
* lisp/obsolete/cl.el: Make alias help say that they are obsolete.
* lisp/obsolete/cl-compat.el (build-klist, safe-idiv)
(pair-with-newsyms): Silence byte-compiler.

 @c There is also cl-mapc, which was called cl-mapc even before cl-lib.el.
 @c But not autoloaded, so maybe not much used?
 
-Since the old @file{cl.el} does not use a clean namespace, Emacs has a
-policy that packages distributed with Emacs must not load @code{cl} at
-run time.  (It is ok for them to load @code{cl} at @emph{compile}
-time, with @code{eval-when-compile}, and use the macros it provides.)
-There is no such restriction on the use of @code{cl-lib}.  New code
-should use @code{cl-lib} rather than @code{cl}.
-
-There is one more file, @file{cl-compat.el}, which defines some
-routines from the older Quiroz @file{cl.el} package that are not otherwise
-present in the new package.  This file is obsolete and should not be
-used in new code.
+The old file @file{cl.el}, as well as the even older
+@file{cl-compat.el}, are deprecated and will be removed in a future
+version of Emacs.  Any existing code that uses them should be updated
+to use @file{cl-lib.el} instead.
