[ARC] Refactor deprecated macros.

xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

	* config/arc/arc-protos.h (arc_register_move_cost): Remove.
	* config/arc/arc.c (arc_register_move_cost): Re-purpose it to
	implement target hook.
	(arc_memory_move_cost): New function.
	(TARGET_REGISTER_MOVE_COST): Define.
	(TARGET_MEMORY_MOVE_COST): Likewise.
	* config/arc/arc.h (REGISTER_MOVE_COST): Remove.
	(MEMORY_MOVE_COST): Likewise.
