<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Utkarsh Saxena (usx95) <details> <summary>Changes</summary> Instead of directly pushing the `Destroy`, we should use `pushFullExprCleanup` which handles conditional branches. This fixes a backend crash due to 89ba7e183e6e2c64370ed1b963e54c06352211db.
