Vectorization, SIMD

[Gerd Möllmann]

Hi Stef,

I've played with this a bit and made notes, which I'd like to share.
Please find attached.

My summary so far: Can be done and it's not that difficult. There is
even some degree of "portability" achievable when writing SIMD code by
hand. What's will be really no fun, from my POV, is configuration stuff,
making it work on N platforms with M compilers and so on.

Don't know, maybe it's best to wait for compilers to get better at
auto-vectorization. Or maybe GCC is better than LLVM in this regard. I
haven't checked that because I can't really use GCC here on macOS.
