The problem is that vla/assumed-shape arrays become `!fir.box<!fir.array<?xTYPE>>` and `!fir.box` is not accepted by the `omp` dialect (at least not by `OpenMP_PointerLikeType`).
Modifying `OpenMP.cpp` to also pass boxes to `copyprivate` results in the following error:
`'omp.single' op operand #0 must be variadic of OpenMP-compatible variable type, but got '!fir.box<!fir.array<?xi32>>'`

Is there a way to get the address of a box, to make it become a `!fir.ref<!fir.box<!fir.array<?xTYPE>>>`?
`fir.box_addr` returns only the boxed value, without the other parameters needed to perform the copy.
