…honGH-15593) With `symtable_visit_expr` now correctly adjusting the recursion depth for named expressions, `symtable_handle_namedexpr` should be leaving it alone. Also adds a new check to `PySymtable_BuildObject` that raises `SystemError` if a successful first symbol analysis pass fails to keep the stack depth accounting clean.
