NEON is the new black: fast JPEG optimization on ARM server

The Qualcomm Centriq CPU is a powerful processor that provides good performance and power efficiency. However, years of Intel leadership in the server and desktop space mean that a lot of software is better optimized for Intel processors. Writing optimizations for ARMv8 is not difficult, and we will be adjusting our software as needed, and publishing our efforts as we go. The updated code can be found on our Github page.
