Implement Neon variance functions using UDOT instruction Accelerate Neon variance functions by implementing the sum of squares calculation using the Armv8.4-A UDOT instruction instead of 4 MLAs. The previous implementation is retained for use on CPUs that do not implement the Armv8.4-A dot product instructions. Bug: b/181236880 Change-Id: I9ab3d52634278b9b6f0011f39390a1195210bc75
