The compiler already does use such a structure, i.e. the highlevel 
(node) code generator calls routines in the backend codegenerator which 
output the actual assembler instructions.

If you would output a macro instead of the indivudual instructions you 
would get what you describe. The current approach is at least as flexible 
though, so I see little benefit.
