A recent RTX cost commit has changed the costs for ARC700 leading to
errors in slsr-13.c test.  This commit fixes this issue by reverting
the cost computation for short instructions.

	* config/arc/arc.c (arc_rtx_costs): All short instructions are
	having a lower cost regardless of the speed option.
