    PR11360: Make @defined and -L play nice
    
    The constant-folding is now enabled for s.listing_mode_vars, despite all
    other optimizations being disabled.  This is needed so we can prune any
    invalid branches that are gated by @defined.
    
    * elaborate.cxx (semantic_pass): Leave the optimization decision to the
      optimization passes themselves.
      (semantic_pass_optimize1): Predicate most optimizations, but enable the
      constant-folding for listing_mode_vars too.
      (semantic_pass_optimize2): Predicate all (1) optimizations.
    * testsuite/semok/defined_list_vars.stp: New test.
