What crash? How did the zero get there? Does this only happen if you
do your optimization loop thing?
In either case, we still want the replaceZero() logic. However that
logic should be aware that the middle argument of a SHLADD is not to
be touched. Otherwise we could end up with an un-emittable
instruction.
