I've attached a patch that will do the optimization you request.
Thanks for looking into this!
It should, however, work for your testcase.
Indeed it does, the combinations I was requesting are performed now.
Unfortunately the different set of temporaries now generated appear
to trigger some other suboptimal behaviour of ivopts, so the end result
is still quite bad (even with Zdenek's patch) -- I'll have to
investigate this further ...
