For large inputs, this runs ~11x faster than Murmur3. My bench drops from 1µs to 88ns. Like x86-64, this runs fastest if we work in 24 byte chunks. 16 byte chunks run at about 0.75x this speed, 8 byte chunks at about 0.4x (which would still be about 5x faster than Murmur3). This'll require plumbing support for opts_crc32 into Chrome first before it can roll. perf.skia.org charts we want to watch: https://perf.skia.org/#5490 Seach for compute_hash in these logs to see the difference: baseline: https://luci-milo.appspot.com/swarming/task/30ba22f3dfe30e10/steps/nanobench/0/stdout trybot: https://luci-milo.appspot.com/swarming/task/30bbc406cbf62d10/steps/nanobench/0/stdout BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2260823002 CQ_INCLUDE_TRYBOTS=master.client.skia:Test-Ubuntu-GCC-GCE-CPU-AVX2-x86_64-Release-SKNX_NO_SIMD-Trybot Review-Url: https://codereview.chromium.org/2260823002
