Expand @defined to support more cases
* tapsets.cxx (var_expanding_visitor::visit_defined_op): If no error was
raised or replacement made on a target_symbol, then its @defined state
is still indeterminate. Some later pass (like @cast) might handle it.
* elaborate.cxx (const_folder::visit_defined_op): Squash any escapees.
* testsuite/semok/thirtysix.stp: Add more variants.
