Merge bitcoin/bitcoin#24946: Unroll the ChaCha20 inner loop for performance
81c09ee45caecf8d9daf6766b94cebf54f3f08cd Unroll the ChaCha20 inner loop for performance (Pieter Wuille)
Pull request description:
Unrolling the inner ChaCha20 loop gives a ~15% speedup for me in the CHACHA20_* benchmarks. It's a simple change, this performance helps with RNG generation, and will matter more for BIP324.
