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

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.
