Right, that's the kind of stuff I was referencing when I was saying we need work in the FE. The DeviceRTL won't be able to look up/write to variables like `kernel_environment` because the FE doesn't generate them yet.

I agree this won't have use to anyone trying to seriously use SPIR-V with OpenMP, but it is useful for anyone working on OMP/SPIR-V. Maybe it's better to put this under a default-off CMake option?
