Can you add this as a test? AFAIS, the tests attached to this patch do not seem to be exercising the `VariadicofVariadic` requirement. An explanation with an example would be great.

1. Fortran Source + OpenMP example that needs a VariadicOfVariadic
2. MLIR OpenMP representation

I am assuming we would need a verifier as well for the map clause.

Can you also restrict this patch to one of the constructs say `target data` for this patch? Once we decide on that then the other two can be easily added in a separate patch.

Why is this needed here?

Nit: can you specify the type here?

There is a `bitn` function in `printSynchronizationHint` and `verifySynchronizationHint`, can that be used here?

Both the input and the CHECK lines in the custom format.
