[llvm] DAG: Replace bitwidth with type in suffix in atomic tablegen ops (PR #94845)

[Fabian Ritter via llvm-commits]

https://github.com/ritter-x2a commented:

The two occurrences of `swap` in the sed command don't match with the definitions in the code ([here](https://github.com/llvm/llvm-project/blob/2e4c06780c14a9c8445129bdbcd15ceaf25e7ecd/llvm/include/llvm/Target/TargetSelectionDAG.td#L1739-L1751)). In AMDGPU, I didn't see a case where that was a problem, but it might be elsewhere.
Other than that and my inline comment, AMDGPU looks fine.
