sparse_base_chol::operator): Likewise.
* dim-vector.h (oct-refcount.h): New included header.
(dim_vector::make_unique, dim_vector::resize): Use OCTREFCOUNT_ATOMIC_DECREMENT
macro and delete rep when refcount reaches 0.
(dim_vector::dim_vector): Use OCTREFCOUNT_ATOMIC_INCREMENT.
(dim_vector::operator=): Use OCTREFCOUNT_ATOMIC_INCREMENT and
OCTREFCOUNT_ATOMIC_DECREMENT.
