Parsing assembly.

Parsing hand-written assembly-language code into machine language,
generating compiled functions and lookup tables, and printing the
results.  I have some very strange names in there because I’m currently
doing something which makes the Xcode debugger think my Function object
is an array, so I can’t inspect it.  I gave everything weird names in
case I was accidentally using a hidden property of NSObject when I was
doing all this parsing, but it didn’t help.
