Summary: When we were first porting to COV5, this lead to some ABI issues due to a change in how we looked up the work group size. Bitcode libraries relied on the builtins to emit code, but this was changed between versions. This prevented the bitcode libraries, like OpenMP or libc, from being used for both COV4 and COV5. The solution was to have this 'none' functionality which effectively emitted code that branched off of a global to resolve to either version. This isn't a great solution because it forced every TU to have this variable in it. The patch in https://github.com/llvm/llvm-project/pull/131033 removed support for COV4 from OpenMP, which was the only consumer of this functionality. Other users like HIP and OpenCL did not use this because they linked the ROCm Device Library directly which has its own handling (The name was borrowed from it after all). So, now that we don't need to worry about backward compatibility with COV4, we can remove this special handling. Users can still emit COV4 code, this simply removes the special handling used to make the OpenMP device runtime bitcode version agnostic.
