nanbield chipstar experiment

[zboszor]

@reibax-marcus FYI

It doesn't work yet.

Thanks for reporting. I currently don't have time to experiment with nanbield, but I will keep it in mind. If I have time at any point I will definitely look into it.

Don't worry. Since chipStar seems to support LLVM 15 and up, mickledore and up can work.

Hopefully PyTorch and other stuff supporting CUDA can be convinced to use chipStar.

chipStar is not a complete CUDA replacement yet. PyTorch disqualifies it in its CMake framework:

warning: cucc is a work-in-progress. It is incomplete and may behave incorrectly.
