Remove CodeGenerationError and make all bytecode generation functions return their results directly instead of wrapping them in CodeGenerationErrorOr. For the few remaining sites where codegen encounters an unimplemented or unexpected AST node, we now use a new emit_todo() helper that emits a NewTypeError + Throw sequence at compile time (preserving the runtime behavior) and then switches to a dead basic block so subsequent codegen for the same function can continue without issue. This allows us to remove error handling from all callers of the bytecode compiler, simplifying the code significantly.
