Make cl-floatp-safe just an alias for floatp

* lisp/emacs-lisp/cl-lib.el (cl-floatp-safe): Make it an alias for floatp.

* lisp/emacs-lisp/cl-macs.el (cl--make-type-test)
(cl--compiler-macro-assoc): Use floatp rather than cl-floatp-safe.

* doc/misc/cl.texi: Remove commented out sections about cl-floatp-safe.
