Well, there is
http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/info-xref.el
but at that speed, it will take you ~ 10 hours to load the page. :(

This doesn't adequately describe the diff (below) between your version
and the version in the Emacs trunk. Also the new version uses a
cl-function (remove-if) at run-time.

;;; Commentary:
! ;; This file implements some simple checking of external cross references in
! ;; info files, by attempting to visit the nodes specified.
;;
! ;; "makeinfo" checks references internal to a document, but not external
! ;; references, which makes it rather easy for mistakes to creep in or node
! ;; name changes to go unnoticed. `Info-validate' doesn't check external
! ;; references either.
! ;;
! ;; `M-x info-xref-check' checks one file. When invoked from an Info-mode or
! ;; texinfo-mode buffer, the current info file is the default at the prompt.
! ;;
! ;; `M-x info-xref-check-all' looks at everything in the normal info path.
! ;; This might be a lot of files but it's a good way to check the consistency
! ;; of the whole system.
! ;;
! ;; Results are shown in a buffer. The format is a bit rough, but hopefully
! ;; there won't be too many problems normally, and correcting them is a
! ;; manual process anyway, a case of finding the right spot in the original
! ;; .texi and finding what node it ought to point to.
! ;;
! ;; When a target info file doesn't exist there's clearly no way to validate
! ;; node references within it. A message is given for missing target files
! ;; (once per source document), it could be simply that the target hasn't
! ;; been installed, or it could be a mistake in the reference.
! ;;
! ;; Indirect info files are understood, just pass the top-level foo.info to
! ;; `info-xref-check' and it traverses all sub-files. Compressed info files
! ;; are accepted too, as usual for `Info-mode'.
! ;;
! ;; `info-xref-check-all' is rather permissive in what it considers an info
! ;; file. It has to be since info files don't necessarily have a ".info"
! ;; suffix (eg. this is usual for the emacs manuals). One consequence of
! ;; this is that if for instance there's a source code directory in
! ;; `Info-directory-list' then a lot of extraneous files might be read, which
! ;; will be time consuming but should be harmless.
! ;;
! ;; `M-x info-xref-check-all-custom' is a related command, it goes through
! ;; all info document references in customizable variables, checking them
! ;; like info file cross references.
;;; Code:
(require 'info)
! (defconst info-xref-results-buffer "*info-xref results*"

;;; Commentary:
! ;; This is some simple checking of external cross references in info files,
! ;; docstrings and custom-links by attempting to visit the nodes specified.
;;
! ;; `M-x info-xref-check' checks a single info file. See the docstring for
! ;; details.
! ;;
! ;; `M-x info-xref-check-all' checks all info files in Info-directory-list.
! ;; This is a good way to check the consistency of the whole system.
! ;;
! ;; `M-x info-xref-check-all-custom' loads up all defcustom variables and
! ;; checks any info references in them.

! ;; source files (and other files).
