dcompute - A library + ldc modifications - can now build a simple add kernel

[Nicholas Wilson via Digitalmars-d-announce]

Available here[1][2], 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 
welcome!

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!
