      Automatically generate texinfo.el internal autoloads

      * lisp/textmodes/texinfo.el: Replace manual autoloads.
      * lisp/textmodes/makeinfo.el (makeinfo-region, makeinfo-buffer)
      (makeinfo-recenter-compilation-buffer):
      * lisp/textmodes/texnfo-upd.el (texinfo-make-menu)
      (texinfo-all-menus-update, texinfo-start-menu-description)
      (texinfo-indent-menu-description, texinfo-master-menu)
      (texinfo-update-node, texinfo-every-node-update)
      (texinfo-sequential-node-update, texinfo-insert-node-lines)
      (texinfo-multiple-files-update):
      Add autoload cookies, and set generated-autoload-file.

This breaks the build:

    ELC      textmodes/makeinfo.elc

  In toplevel form:

I don't think I understand how texinfo-loaddefs.el was supposed to be
created.  What am I missing?
