In the GHC back end I seem to remember strictness gives a 10%
performance improvement, but let motion gives a 30% improvement - its
quite likely that .NET will benefit more from strictness, but still
the general optimisation is probably going to be a bigger win.

I think basic strictness information gained about 5% in the Javascript
Yhc backend, so not great amounts.

The optimiser does generalised deforestation, and loads of other cool
tricks, so I'm hoping for at least 50% over the normal Yhc code :)
