[Patch, fortran] [15/66] inline sum and product: Interfaces changes: obtain name more simply

[Mikael Morin]

This is a follow-up to the previous patch. It symplifies name obtention
so that later we can change structs with less pain. :-)
OK?

        * trans-array.c (gfc_trans_array_bound_check): Use ss argument
        to get name.
