rs6000: Move processor_costs to header

This moves the processor_costs structure declaration to the rs6000.h
header file, so that things in other files can use it (not just things
in rs6000.c).


	* config/rs6000/rs6000.c (processor_costs): Move to ...
	* config/rs6000/rs6000.h: ... here.
	(rs6000_cost): Declare.
