URL: https://github.com/llvm/llvm-project/commit/a84599f177a67d4a8c1c30ccd96c99fa40af75f7 DIFF: https://github.com/llvm/llvm-project/commit/a84599f177a67d4a8c1c30ccd96c99fa40af75f7.diff LOG: [OpenCL] Implement extended subgroups fully in headers. Extended subgroups are library style extensions and therefore they require no changes in the frontend. This commit: 1. Moves extension macro definitions to the internal headers. 2. Removes extension pragmas because they are not needed.
