Adapt the assembler to the changes on the parser

As of 184c39579227 ("Re-work the parser from scratch") the parser has a
proper AST, and the assembler has to traverse it accordingly.

Moreover, the assembler has been stripped from a lot of unneeded memory
allocations and it's overall more keen on using mere references when
possible.
