This is a peace-of-mind change to make sure that delayed-zeroed memory (in the large alloc case) is globally visible from the moment the allocation is published back to the caller. The way it's written right now is good enough for the garbage collector (we already have a publication barrier for a nil span.largeType, so the GC will ignore the noscan span) but this might matter for user code on weak memory architectures.
