I've been working on new optimization passes for Hoopl to get
the code back to the quality of the old code generator.
With the new optimization pass, the binaries in the test suite
are, on average, 7% larger than the old code generator.
Here are the worst offenders, with T3294 clocking in with a whopping
112% increase in size.

I am planning on doing similar tests on nofib.
This is great. The results are not encouraging, but at least you can
easily find good candidates to investigate. Don't start with T3294 -
look at the really small modules first.
Cheers,
