[PATCH] D130096: [Clang][AMDGPU] Emit AMDGPU library control constants in clang

[Joseph Huber via Phabricator via cfe-commits]

Changing to `linkonce` linkage. According to the LLVM spec this should have the
expected behaviour where a single definition is kept at link-time for each
module. I tested this with a sample `HIP` program and it had the desired
behaviour. I could add a test attempting to show this if needed.
