arm.c (arm_is_xscale): Rename to arm_arch_xscale. 

2003-05-15  Philip Blundell  <philb@gnu.org>

	* config/arm/arm.c (arm_is_xscale): Rename to arm_arch_xscale.
	All uses updated.
	(arm_tune_xscale): New variable.
	(arm_override_options): Set it.
	(arm_adjust_cost): Use it in place of arm_arch_xscale.
	(arm_gen_load_multiple): Likewise.
	(arm_gen_store_multiple): Likewise.
	* config/arm/arm.md (is_xscale): Likewise.
	* config/arm/arm.h (arm_tune_xscale): Declare.
