RFR: 8337720: Test com/sun/jndi/dns/ConfigTests/Timeout.java fails with C1 mode by fastdebug binary

[SendaoYan]

Hi all,
The test `com/sun/jndi/dns/ConfigTests/Timeout.java` fails with `-Xcomp -XX:TieredStopAtLevel=1` jvm options by fastdebug binary. In C1 mode and with debug binary, the JIT comple time longger than -Xmixed  and release binary is accatable. So this should not report fails with `-Xcomp -XX:TieredStopAtLevel=1` jvm options by fastdebug binary.
Thus, this test should be skip when run with `-Xcomp -XX:TieredStopAtLevel=1` jvm options by fastdebug binary.
