I looked at this a little and in fact the boot code that I have written
does tell you exactly which autoloads you need to get temacs to work --
it's not very many, I think that there are only 10 or so (bytecomp.el
for instance).

Of course, this is 10 autoloads PLUS all of the non-auto loads in
loadup.el. My own feeling is that this is a bit unclean at the moment;
given that loadup.el is supposed to support temacs till the point that
it dumps, probably all of the autoloads used for this process should be
explicitly in loadup; or, alternatively, we should have very non-auto
loads in loadup and do everything via autoload.
