This introduces a new pass to lower from a flattened, target-independent form of CIR to a form that uses Itanium-specific representation for exception handling. It also includes a small amount of code needed to lower the Itanium form to LLVM IR. Substantial amounts of this PR were created using agentic AI tools, but I have carefully reviewed the code, comments, and tests and made changes as needed.
