I got rid of most of the autoloads in the preloaded files a couple of
years ago, this must have fallen through the cracks.
Skipping register.el while creating loaddefs.el would be wrong, nothing
else would create the register bindings then.
And there's 3 autoloads more in composite.el, that's all the autoloads
in the unconditionally preloaded files.
Given that there's so few autoloads left, it does not seem like a good
idea to change the build system instead of just removing them.

More, for the specific case of ediff-hook.el, IMO the best thing to do
is got fold the emacs specific contents of that file into menu-bar.el
and get rid of it.  Almost all of the menu creation happens in menu-bar.el...
