[13] RFR(T) 8223380: [Graal] compiler/c2/Test8062950.java failed with time out.

https://bugs.openjdk.java.net/browse/JDK-8223380

We should not run Java Graal with -XX:-TieredCompilation because Graal will be executed by 
Interpreter instead of bean compiled with C1. With -Xcomp and -Xbatch it is worse because test 
execution is blocked until compilation is finished - that is why such tests are slow with Graal.

Put the test on Graal's problem list with umbrella bug:

We will run these tests with these flags when libgraal is introduced in JDK (JDK-8223220).
