SM3 acceleration with SM3 hardware instruction on aarch64
SM3 hardware instruction is optional feature of crypto extension for
aarch64. This implementation accelerates SM3 via SM3 instructions. For
the platform not supporting SM3 instruction, the original C
implementation still works. Thanks to AliBaba for testing and reporting
the following perf numbers for Yitian710:
