[PATCH AArch64 2/2] Replace temporary inline assembler for vget_high

	* config/aarch64/arm_neon.h (__GET_HIGH): New macro.
	(vget_high_f32, vget_high_f64, vget_high_p8, vget_high_p16,
	vget_high_s8, vget_high_s16, vget_high_s32, vget_high_s64,
	vget_high_u8, vget_high_u16, vget_high_u32, vget_high_u64):
	Remove temporary __asm__ and reimplement.
