Frank Barchard 790e0634a8 Port HammingDistance_NEON 32 bit code to 64 bit 
The 32 bit version of HammingDistance_NEON accumulates
using vertical add and paired adds, which takes 3 instructions
instead of 4.
The instructions are also portable between 32 and 64 bit.

Was BenchmarkHammingDistance_Opt (105 ms)
Now BenchmarkHammingDistance_Opt (90 ms)

BenchmarkHammingDistance_Opt (90 ms)
