	* config/arm/predicates.md (neon_struct_operand): Make a normal
	predicate.
	(neon_struct_or_register_operand): New predicate.
	* config/arm/neon.md (movmisalign<mode>): Replace predicates
	with neon_struct_or_register_operand.
	(*movmisalign<mode>_neon_store, *movmisalign<mode>_neon_load): Use
	neon_struct_operand instead of memory_operand.
