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.
