Yes, when SRA decomposes a copy it leaves out padding which means we later fail
to apply store-merging and thus end up generating worse code for a simple
aggregate copy. SRA assumes the total scalarization transform allow followup
optimizations, if this doesn't happen it's hardly a profitable transform.
