Martin Willi b1ccc8f4b6 crypto: poly1305 - Add a four block AVX2 variant for x86_64
Extends the x86_64 Poly1305 authenticator by a function processing four
consecutive Poly1305 blocks in parallel using AVX2 instructions.

For large messages, throughput increases by ~15-45% compared to two
block SSE2:
