    fortran: array descriptor: Move rank offset construction [PR122521]

    The construction of the array descriptor debug info uses the rank field
    layout information to generate an expression for the rank in
trans-type.cc's
    `gfc_get_array_descr_info'.

    This change moves the rank offset construction to trans-descriptor.cc's
    `gfc_get_descriptor_offsets_for_info', so that the layout of the rank field
    doesn't need to be known outside of trans-descriptor.cc.

            PR fortran/122521

    gcc/fortran/ChangeLog:

            * trans-descriptor.cc (gfc_get_descriptor_offsets_for_info): Remove
            the dtype offset argument and add a rank offset argument.  Set the
            value of that offset.  Use a variable to factor repeated accesses
to
            TYPE_FIELDS (type).
            * trans-types.cc (gfc_get_array_descr_info): Update caller.  Create
            the rank expression using the just obtained rank offset.
