What's a 32-bit index type? The index type has a platform-dependent bitwidth. I'm not sure what the semantics of this operation is:
```mlir
%c0_i32 = llvm.mlir.constant(1 : index) : i32
```
Is it `index` or `i32`? It can't be both.

It may be worth asking on Discourse/Discord for further clarification.
