RFR: 8368866: compiler/codecache/stress/UnexpectedDeoptimizationTest.java intermittent timed out

[SendaoYan]

Hi all,

When I run test compiler/codecache/stress/UnexpectedDeoptimizationTest.java standalone, test occupy about 6 CPU threads.

The default timeout factor was change from 4 to 1 by [JDK-8260555](https://bugs.openjdk.org/browse/JDK-8260555). This make test compiler/codecache/stress/UnexpectedDeoptimizationTest.java intermittent timed out when this test run with other tests simultancely, because this is stress test which may affect by other tests.

So I want to change the default timeout value from 120 to 240, this will make this test run success steady.
