crypto: x86/sm3 - add AVX assembly implementation
This patch adds AVX assembly accelerated implementation of SM3 secure
hash algorithm. From the benchmark data, compared to pure software
implementation sm3-generic, the performance increase is up to 38%.
The main algorithm implementation based on SM3 AES/BMI2 accelerated
work by libgcrypt at:
https://gnupg.org/software/libgcrypt/index.html
Benchmark on Intel i5-6200U 2.30GHz, performance data of two
implementations, pure software sm3-generic and sm3-avx acceleration.
The data comes from the 326 mode and 422 mode of tcrypt. The abscissas
are different lengths of per update. The data is tabulated and the
unit is Mb/s:
update-size | 16 64 256 1024 2048 4096 8192
