[Patch, fortran] [12/66] inline sum and product: Preliminary cleanups: Stop loop before end marker.

[Mikael Morin]

We should not be writing to gfc_ss_terminator.
It is working without this patch because gfc_ss_terminator's next pointer is
NULL, so the loop stops just after it, and because we are writing zero to
gfc_ss_terminator, but it is already all zeros anyway.
OK?

        * trans-array.c (gfc_trans_scalarizing_loops): Stop loop before end
        marker, not after it.
