>From what I understood when trying to implement this lowering:
The `declMapperOp's` `parentOp` must have a symbol table as it declares a new
symbol, this is why I hoisted it to the `ModuleOp` from the `funcOp`.
The `declMapperOp` also relies on a var definition which is immediately used in
it's map clause. I can't put this var inside a region, as then it can't be used
in the map clause. As such, this new `alloc` is also moved to just before the
`declMapperOp`.
Do you have any suggestion to do this in a different way?
