What kind of instruction set do you have in mind?  The closer it is to 
one we already target, the easier this is, but it is quite possible to 
write a back-end for a relatively new one.

You can use the interpreter as a simulator for a very abstract machine 
(and extend it with any performance metrics you want).   How do you 
want to use it?
