This commit changes the builders of the `llvm.mlir.addressof` operations
to no longer produce typed pointers.
As a consequence, a GPU to NVVM pattern had to be updated, that still
relied on typed pointers.

Subject: [PATCH 1/4] [MLIR][LLVM] Change addressof builders to use opaque
pointers
This commit changes the builders of the `llvm.mlir.addressof` operations
to no longer produce typed pointers.
As a consequence, a GPU to NVVM pattern had to be updated, that still
relied on typed pointers.
