If you want to run test262 tests through V8's harness, tools/run-tests.py will be adding the flag to turn on TCO using the file in test/test262/test262.status. Back in 5.1 days, we just passed --harmony for all tests, but now the status file or feature flags determine which flags are passed. In 5.1, --harmony turned on --harmony-tailcalls and made the test pass; now, test262.status explicitly lists the tests that depend on TCO and passes --harmony-tailcalls for them.
