Add an empty constructor shortcut to build_vector_from_ctor
Empty vector constructors are equivalent to zero vectors. If we handle
that case directly, we can support it for variable-length vectors and
can hopefully make things more efficient for fixed-length vectors.
This is needed by a later C++ patch.
