Added some DEBUG() prints to make it clearer what the mach-o passes are doing. NFC.

We had some DEBUG prints these passes, but add more so that its clear where we are dumping
things, and what state we are in when we do so.

I'll be adding more and more DEBUG printing to try make it easier to observe whats going on
without having to attach a debugger.
