…but I'm still struggling with rust w/ asm. Along my journeys, however, I found this repo https://github.com/WojciechMula/sse-popcount/ which has tons of competing simd implementations for both intel and arm.

…(and AVX-512 if present) is actually faster yet [1] - at least for 512 byte inputs or larger. [1]: https://github.com/WojciechMula/sse-popcount

…seems it's such due to my indolence/stupidity. I've just merged pull request by Simon Lindholm ( https://github.com/WojciechMula/sse-popcount/pull/2 ) with manually unrolled loops and it made the AVX2 code faster 40% than POPCNT.
