I didn't realize these had made it into the 18.0 release when I suggested that we could remove them. We would need at least one release where they are marked as deprecated, but since they are standard gcc options, maybe it makes sense to just keep them and have them alias to the new option as:

-fcx-limited-range --> -fcomplex-arithmetic=basic
-fcx-fortran-rules --> -fcomplex-arithmetic=improved
-fno-cx-limited-range --> -fcomplex-arithmetic=full
-fno-cx-fortran-rules --> -fcomplex-arithmetic=full
