In order to unit test that this change doesn't regress the handling of "const Symbol(...)", it was necessary to expand TestTypeProvider's Symbol class to include the Symbol constructor. Note: with this fix, analyzer detected a previously unknown flaw in tests/language/switch_case_test.dart: class D didn't implement a getter for x. Test updated accordingly. This change breaks test lib/_internal/compiler/samples/jsonify/jsonify by changing analyzer's handling of bool.fromEnvironment(). I plan to address this in a future changelist.
