Available here, it can now build a simple add kernel for
both CUDA (.ptx) and OpenCL (.spv) (and of course the host code)
in one compiler invocation.
A lot of things are still hardcoded and the optimisations need to
tuned a bit more but it works.
Any and all testing, feedback,bug reports and pull requests
I'll be working on it the next two weeks, after which I go back
to uni and will have less time to work on it, so the more feed
back the better!
