George Steed 4f52235a67 [AArch64] Replace SHRN{,2} pair by UZP2 in DivideRow_16_NEON 
Shift instructions have worse throughput than other permute instructions
on some micro-architectures, and we can avoid the need for two separate
narrowing instructions by taking the high halves of each lane directly
through use of the UZP2 instruction.

Reduction in runtime for DivideRow_16_NEON:

 Cortex-A55:  -6.2%
Cortex-A510: -30.0%
 Cortex-A76: -11.9%
  Cortex-X2: -46.8%
