Implement new intermediate stage

Massive improvement. Label references can be used anywhere in the
program, with the program being assembled repeatedly until all labels
have stabilised. The bytecode stage will just be a tiny stage tacked
onto the end, rather than the old bytecode stage that would resolve
labels and expressions.
