Reverts llvm/llvm-project#79586 This broke the AMDGPU OpenMP Offload buildbot. The typical error message was that the GPU attempted to read beyong the largest legal address. Error message: AMDGPU fatal error 1: Received error in queue 0x7f8363f22000: HSA_STATUS_ERROR_MEMORY_APERTURE_VIOLATION: The agent attempted to access memory beyond the largest legal address.
