[PATCH AArch64] Add a builtin for rbit(q?)_p8; add intrinsics and tests.

gcc/:

	* config/aarch64/aarch64-simd.md (aarch64_rbit<mode>): New pattern.
	* config/aarch64/aarch64-simd-builtins.def (rbit): New builtin.
	* config/aarch64/arm_neon.h (vrbit_s8, vrbit_u8, vrbitq_s8, vrbitq_u8):
	Replace temporary asm with call to builtin.
	(vrbit_p8, vrbitq_p8): New functions.

gcc/testsuite/:

	* gcc.target/aarch64/simd/vrbit_1.c: New test.
