[PATCH 3/20] aarch64: Use RTL builtins for vpaddq intrinsics

[Jonathan Wright via Gcc-patches]

Hi,

As subject, this patch rewrites the vpaddq Neon intrinsics to use RTL
builtins rather than inline assembly code, allowing for better scheduling
and optimization.

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

Ok for master?

Thanks,
Jonathan
