…which is why it seems like I have to keep fixing bugs every time I try to use 

If CANNOT_DUMP mode worked reliably, I’d think it would be the logical starting 
point for this work — it’s already compiling with the expectation that we’ll be 
loading the Lisp code when the user starts it up rather than preparing for 
unexec and a second invocation of main().  Changing the thing we load at 
startup from loadup.el to dumped.elc should be pretty minor.

I’m trying CANNOT_DUMP out right now.  As soon as I’ve got it bootstrapping 
again, I’ll try pulling in the other changes.
