George Steed 95eed2b75f [AArch64] Add Neon dot-product implementation of HammingDistance
We can use the Neon dot-product instructions as a slightly faster
widening accumulation. This also has the advantage of widening to 32
bits so avoids the risk of overflow present in the original Neon code.

Reduction in runtimes observed for HammingDistance compared to the
existing Neon code:

 Cortex-A55:  -4.4%
Cortex-A510: -26.5%
 Cortex-A76:  -8.1%
Cortex-A720: -15.5%
  Cortex-X1:  -4.1%
  Cortex-X2:  -5.1%
