The number of operations dedicated to CUF grew and where all still in FIR. In order to have a better organization, the CUF operations, attributes and code is moved into their specific dialect and files. CUF dialect is tightly coupled with HLFIR/FIR and their types.
The CUF attributes are bundled into their own library since some HLFIR/FIR operations depend on them and the CUF dialect depends on the FIR types. Without having the attributes into a separate library there would be a dependency cycle.
