ARM64 NEON SIMD implementation of Huffman encoding Full-color compression speedups relative to previous commits: Cortex-A53 (Nexus 5X), Android, 64-bit: 1.1-13% (avg. 6.0%) Cortex-A57 (Nexus 5X), Android, 64-bit: 0.0-22% (avg. 6.3%) Refer to #47 and #50 for discussion Closes #50 Note that this commit introduces a similar /proc/cpuinfo parser to that of the ARM32 implementation. It is used to specifically check whether the code is running on Cavium ThunderX and, if so, disable the ARM64 SIMD Huffman routines (which slow performance by an average of 8% on that CPU.)
