[PATCH] aarch64: Use type-qualified builtins for ADDV Neon intrinsics

[Jonathan Wright via Gcc-patches]

Hi,

This patch declares unsigned type-qualified builtins and uses them to
implement the vector reduction Neon intrinsics. This removes the need
for many casts in arm_neon.h.

Regression tested and bootstrapped on aarch64-none-linux-gnu - no
issues.

Ok for master?

Thanks,
Jonathan
