Another case
unsigned bar (unsigned int *x)
{
int sum = 0;
for (int i = 0; i < 16; ++i)
sum += x[i];
return sum;
}
where an intermeditate result of the reduction chain is live.

So to outline the desired approach again the idea is to make the SCC finding

need to handle conversions as reduction code...) but t

More "correct" would be to replace the reduction in sum with one using an
unsigned int type. Not sure where this kind of transform would fit best,
but as it's an enablement for vectorization I suppose the v
