Don't targets like MSP430 and MBlaze serve as good stubs?

It's a good question... I think people are looking for something
minimal, so they already know that there are no "unnecessary" stuff...

I think that you need two things:

1. A direct-as-possible mapping in between the DAG and the stub backend
instructions

2. The features of the backend are all configurable (legal datatypes and
instructions, what is promoted to what, etc.) so that we can test as much of the
legalizer's parameter space as possible.
