URL: https://github.com/llvm/llvm-project/commit/fe13002bb37caf7425dfdb56b8f891c3f33b54b6 DIFF: https://github.com/llvm/llvm-project/commit/fe13002bb37caf7425dfdb56b8f891c3f33b54b6.diff LOG: [HLSL] Add __builtin_hlsl_create_handle This is pretty straightforward, it just adds a builtin to return a pointer to a resource handle. This maps to a dx intrinsic. The shape of this builtin and the underlying intrinsic will likely shift a bit as this implementation becomes more feature complete, but this is a good basis to get started. Depends on D128569.
