https://github.com/kbenzie created https://github.com/llvm/llvm-project/pull/149283

* x86_64-unknown-linux-gnu checks tested on a system with AMD Ryzen 3950X.
* amdgcn-amd-amdhsa checks tested on a system with AMD Radeon 6700XT using ROCm 6.3.
* nvptx64-nvidia-cuda checks tested on a system with NVIDIA RTX 3060 Ti using
* CUDA 12.8.
* Use XFAIL for checks which are always failing
* Use UNSUPPORTED for checks which are flaky
