I suspect this will often fail to work because autoloads are often
generated by a fresh new session where `my-autoloadable-macro-to-expand`
will not yet be defined.

So at the very least, your patch should make sure to signal an error
when the cookie is of the form `;;;autoload-expand` by the head is not
currently defined as a macro.

I've been wanting to add the feature you propose, but this "macro is not
defined" has gotten in the way until now.  I think we need to add
something like a file-local `autoload-requires-for-macros`.
