[ARC][COMMITTED] Fix slsr-13 regressions.

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.

2019-06-28  Claudiu Zissulescu  <claziss@synopsys.com>

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