documentation for this:   - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that     generates unnecessary code in seaice_lsr_ad   - add more store directives in seaice_lsr to avoid unnecessary code     in seaice_lsr_ad   - exclude some residual computations in seaice_lsr when     ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code     in seaice_lsr_ad   - add more storing, a new tape (model/src/the_main_loop.F) and     another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey     and klockey should be checked by a specialist) The above changes do not alter the verification results
documentation for this:
  - (pkg/autodiff) remove storing/restoring of seaiceMaskU/V that
    generates unnecessary code in seaice_lsr_ad
  - add more store directives in seaice_lsr to avoid unnecessary code
    in seaice_lsr_ad
  - exclude some residual computations in seaice_lsr when
    ALLOW_AUTODIFF_TAMC is defined in order to avoid unnecessary code
    in seaice_lsr_ad
  - add more storing, a new tape (model/src/the_main_loop.F) and
    another key for SEAICE_LSR_VECTORIZE_ZEBRA (the local keys ilockey
    and klockey should be checked by a specialist)
The above changes do not alter the verification results

  - modify ( define SEAICE_VECTORIZE_LSR and SEAICE_LSR_ADJOINT_ITER )
    and update lab_sea after previous changes in pkg/seaice below
