Hi All,

This implements the new widening reduction optab in the backend.
Instead of introducing a duplicate definition for the same thing I have
renamed the intrinsics defintions to use the same optab.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Ok for master?

Thanks,
Tamar

gcc/ChangeLog:

	* config/aarch64/aarch64-simd-builtins.def (saddlv, uaddlv): Rename to
	reduc_splus_widen_scal_ and reduc_uplus_widen_scal_ respectively.
	* config/aarch64/aarch64-simd.md (aarch64_<su>addlv<mode>): Renamed to
	...
	(reduc_<su>plus_widen_scal_<mode>): ... This.
	* config/aarch64/arm_neon.h (vaddlv_s8, vaddlv_s16, vaddlv_u8,
	vaddlv_u16, vaddlvq_s8, vaddlvq_s16, vaddlvq_s32, vaddlvq_u8,
	vaddlvq_u16, vaddlvq_u32, vaddlv_s32, vaddlv_u32): Use it.
