One more thing;
Is there a limit where the loop body gets so large that we
want to decide that "gah, this sucks, no point in unrolling this"?
I imagine as the loops get large there will be a case of
diminishing returns from the unrolling?
I think only backend can say something to that. You e.g. give backend
unrolled and non-unrolled versions and backend decides which one is
better (after applying additional optimizations)...
