GHC back-end

For those interested in improving the performance of GHC's generated
code, especially in the area of tight loops, I have collected a bunch of
ideas on this wiki page:

This is partly the outcome of a discussion between myself and Roman
Leshchinskiy, who is working on nested data parallelism.  Roman has
already implemented some special-case optimisations to improve
performance of tight loops, and he plans to do more.

If you have any thoughts, ideas, or comments on the proposals, please
let us know!

Also, it's not clear if/when any of this will get done.  Talented
compiler hackers are most welcome to help out.
