T5321FD and T5321Fun performance improvements

I'm not really concerned that tests improved, but I wonder whether this improvement was caused by recent fix for #8083 pushed by Simon Marlow. Given performance changes I reported in #8082 I simply wonder how sensitive is the code generation. I observed one case where performance improves by 20% just by accident. Perhaps this would be another such case?

If no one remembers, just accept the new values!

|  T5321FD and T5321Fun are failing with HEAD - performance stat is too good.
|  Looks like the allocation has decreased. Did anyone notice when this improvement
|  happened?
