[PATCH 2/20] aarch64: Use RTL builtin for vq[r]dmulh[q]_n intrinsics

[Jonathan Wright via Gcc-patches]

Hi,

As subject, this patch rewrites the vq[r]dmulh[q]_n 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
