Try to add proper side effects for triton operations. The CSE pass could fail, hang, or output incorrect IRs for unknown reasons, if side effects are not defined properly. For instance, suppose we have two shared memory tensors: ``` %a = triton_gpu.alloc_tensor shape0, share_encoding0 %b = triton_gpu.alloc_tensor shape0, share_encoding0 ``` The CSE pass will consider `%a` and `%b` are the same thing and eliminate one of them, resulting in mysterious outcomes.
