        PR fortran/88929
        * trans-array.c (gfc_conv_descriptor_elem_len): New function.
        * trans-array.h : Add prototype for above.
        * trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Take account of
        assumed rank arrays being flagged by rank = -1 in expressions.
        Intent in arrays need a pointer to a copy of the data to be
        assigned to the descriptor passed for conversion. This should
        then be freed, together with the CFI descriptor on return from
        the C call.
