In my experimentation, I had found that most non-SSAable expressions were converted to autotmp variables during AST evaluation. However, this was not true generally, as witnessed by issue #35213, which has a non-SSAable field reference of a struct that is not converted to an autotmp. So, I fixed openDeferSave() to handle non-SSAable nodes more generally, and make sure that these non-SSAable expressions are not evaluated more than once (which could incorrectly repeat side effects).
