This patch adds the NEON acceleration implementation of the SM3 hash
algorithm. The main algorithm is based on SM3 NEON accelerated work of
the libgcrypt project.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 326 mode
of tcrypt, and compares the performance data of sm3-generic and sm3-ce.
The abscissas are blocks of different lengths. The data is tabulated and
the unit is Mb/s:
update-size | 16 64 256 1024 2048 4096 8192
---------------+--------------------------------------------------------
sm3-generic | 185.24 221.28 301.26 307.43 300.83 308.82 308.91
sm3-neon | 171.81 220.20 322.94 339.28 334.09 343.61 343.87
sm3-ce | 227.48 333.48 502.62 527.87 520.45 534.91 535.40
