Unfortunately I did not get around to do actual auto-vectorisation in my
2009 GSoC project.

I've since continued to work on autovectorisation but switched to an
unrolling-based approach instead of the dependence-based approach
planned for the GSoC 2009 project. I have a basic unrolling-based
autovectoriser working, and plan to start getting this work merged into
mainline LLVM somewhen in mid July. As the vectorisation pass is pretty
stand-alone and only needs a few minor changes to the loop unroller, I
expect merging to be pretty straightforward.
