SIMD support

Would it be of interest to add SIMD support? For example Numpy uses https://github.com/mathlibrary/usimd

numo-narray also already has SIMD support. https://github.com/ruby-numo/numo-narray/pull/111

Thanks. This adds SSE instructions. However, AVX, neon and possibly SVE instructions may also be helpful:

  • https://github.com/gcc-mirror/gcc/blob/master/gcc/config/aarch64
  • https://github.com/gcc-mirror/gcc/tree/master/gcc/config/i386

Further conditional compilation options could be used

It would be nice to have AltiVec as well, but presently the core doesn’t even compile: https://github.com/ruby-numo/numo-narray/issues/215
