I would in principle say no - we can instead improve the middle-end here. But
it may pay off to not generate a loop for short vectors in case the resulting
IL is smaller for example. Of course it would duplicate logic in the frontend
if that is not already available, so from a middle-end point of view we should
fix it there instead (the same problems happen for C and C++). See PR34223.
