[05/30] Changes to arm

From: Aaron Sawdey <acsawdey@linux.ibm.com>

	* config/arm/arm-protos.h: Change movmem to cpymem in names.
	* config/arm/arm.c (arm_movmemqi_unaligned, arm_gen_movmemqi,
	gen_movmem_ldrd_strd, thumb_expand_movmemqi) Change movmem to cpymem.
	* config/arm/arm.md (movmemqi): Change movmem to cpymem.
