Lowering CIR to SCF?

[jelvani]

What is the status of the -cir-mlir-scf-prepare pass (listed here) for cir-opt? I am using llvmorg-21.1.7 and I do not see any passes for cir-opt or mlir-opt related to lowering CIR to SCF.
Are there any other ways to do this as of now?
I need to compile C code to MLIR SCF and the only other way I know of is with Polygeist which throws errors for the code I have and as far as I know is no longer active.
