pub fn md5_x8(msgs: [&[u8]; 8]) -> [[u8; 16]; 8]Expand description
MD5 of EIGHT equal-length messages at once — AVX2 8-way multi-buffer, twice the width of md5_x4.
All eight ABCD states advance in one __m256i (lane j = message j). Falls back to two md5_x4
passes without AVX2. Byte-identical to md5 per lane; the high-throughput path for hashing many
same-size records (bulk name-based ids, dedup/content keys).
