There are no flagless tests in `compiler/c2/irTests`, though. AFAIU, the intent for `vm.flagless` is to skip non-default run configurations for the tests which are driven internally with _complete overwrite_ of passed test options. In other words, `vm.flagless` is there to mark the tests where putting different VM options on the driver code does not really affect the test. IR tests are not like this, so `vm.flagless` makes little sense there. (One can imagine putting more compiler stress options to TEST_VM_OPTS...)
