I'll create a new PR for that, currently `AMDGPUToROCDL` doesn't support setting `index-bitwidth`. For testing that one needs to use `gpu-to-rocdl`.

I was also thinking in changing the  AMDGPU ops to take `index` instead of `i32` and convert to `i32` during lowering. That would make the lowering less buggy prone.
