[ignition] Improve code generation for TestTypeOf. The code generated for the TestTypeOf bytecode was not ideal, mostly because of the default case that just aborted. If we do CSA_ASSERT to check the validity of the literal_flag instead anf then just use the last label as the default, the bytecode handler no longer builds a stack frame and generated code quality is now really close to ideal. The TestTypeOf bytecode handler was found to be among the three hottest bytecode handlers in the Speedometer/AngularJS benchmark.
