	* config/arm/arm-builtins.c (neon_builtin_datum): Rename to ..
	(arm_builtin_datum): ... this.
	(arm_init_neon_builtin): Rename to ...
	(arm_init_builtin): ... this. Add a new parameters PREFIX
	and USE_SIG_IN_NAME.
	(arm_init_neon_builtins): Replace 'arm_init_neon_builtin' with
	'arm_init_builtin'. Replace type 'neon_builtin_datum' with
	'arm_builtin_datum'.
	(arm_init_vfp_builtins): Likewise.
	(builtin_arg): Rename enum's replacing 'NEON_ARG' with
	'ARG_BUILTIN' and add a 'ARG_BUILTIN_NEON_MEMORY.
	(arm_expand_neon_args): Rename to ...
	(arm_expand_builtin_args): ... this. Rename builtin_arg
	enum values and differentiate between ARG_BUILTIN_MEMORY
	and ARG_BUILTIN_NEON_MEMORY.
	(arm_expand_neon_builtin_1): Rename to ...
	(arm_expand_builtin_1): ... this. Rename builtin_arg enum
	values, arm_expand_builtin_args and add bool parameter NEON.
	(arm_expand_neon_builtin): Use arm_expand_builtin_1.
	(arm_expand_vfp_builtin): Likewise.
	(NEON_MAX_BUILTIN_ARGS): Remove, it was unused.
