Oh, I see what you mean now.

So NVPTXPeephole should be guarded by `CodeGenOpt::None` and thus is safe to skip.

`NVPTXLowerKernelArgs` is unsafe to skip. See my inlined comments.

----------------
handleByValParam is necessary for correctness, so NVPTXLowerKernelArgs can't be skipped unless we separate handleByValParam out to another pass.
