Reduce memcpy calls by pushing empty items first

This can only be used in certain situations, and is mostly useful when
the pointer is needed to initialize the item anyway. But by pushing an
empty item and returning the pointer, I can then initialize in the
vector directly instead of initialize and push (with memcpy()).
