	* gcc.target/aarch64/advsimd-intrinsics/arm-neon-ref.h (result):
	Add poly64x1_t and poly64x2_t cases if supported.
	* gcc.target/aarch64/advsimd-intrinsics/compute-ref-data.h
	(buffer, buffer_pad, buffer_dup, buffer_dup_pad): Likewise.
	* gcc.target/aarch64/advsimd-intrinsics/p64_p128.c: New file.
	* gcc.target/aarch64/advsimd-intrinsics/vreinterpret_p128.c: New file.
	* gcc.target/aarch64/advsimd-intrinsics/vreinterpret_p64.c: New file.
