So accelerate the CRC-32 library code on arm64 to use a 4-way interleave, using PMULL instructions to implement the folding. On Apple M2, this results in a speedup of 2 - 2.8x when using input sizes of 1k - 8k. For smaller sizes, the overhead of preserving and restoring the FP/SIMD register file may not be worth it, so 1k is used as a threshold for choosing this code path. The coefficient tables were generated using code provided by Eric.
