Too many changes to list, but broadly:
* Remove Intel GPU support from the compiler
* Add AMD GPU support to the compiler
* Remove Intel GPU host code
* Add AMD GPU host code
* More device instructions. From 40 to 68
* More host functions. From 48 to 184
* Add proof of concept implementation of OptiX framework
* Add minimal support of cuDNN, cuBLAS, cuSPARSE, cuFFT, NCCL, NVML
* Improve ZLUDA launcher for Windows
* Update ze_loader.lib to the newest version
* Export _ptsz/_ptds for which we have a legacy stream implementations
* Stop producing build logs if we are not looking at them anyway
zluda_dump can already create traces of GPU execution, this script can replay those traces.
Additionally, changed added just enough code in core ZLUDA to support simple PyCUDAexecution
Fixes issues pointed out in #27:
* spirv_tools-sys was build in non-test profiles
* By default ZLUDA dll has a wrong name
* We relied on third-party OpenCL installation on Windows
* We encouraged building debug configuration
* We didn't provide build information for developers (cmake, python, submodules)
