?

If we specify requirements as follows: REQUIRES: flang, amdgcn-amd-amdhsa then we will launch this test only for flang and AMDGPU (source: https://llvm.org/docs/TestingGuide.html ) . If we skip amdgcn-amd-amdhsa requirement, then we can launch the test with Flang + nvptx64-nvidia-cuda.

Ah, my bad! I didn't notice the LTO part in nvptx64-nvidia-cuda-LTO!
