structurize-returns uses scope-end blocks recorded during codegen to transform the control flow. When "cleanup" blocks are generated (for example for lifetime-markers), structurize-returns as is cannot transform the control flow safely. This change disables structurize-returns and emits a warning when cleanup blocks are detected in the affected function. (cherry picked from commit 93f43ec)
