There are a couple of issues here, first there is a missed optimization to sink
the load (there is a bug about that). In fact this is all related to that bug.
Also there is a front-end bug having the load there in the first place so
confirmed.
If you look to see what causes the two loads to become one, that would be FRE
and that is only because the front-end is saying the first load is not zero. I
bet we could get into real trouble with real optional arguments if this is not
done correctly.
