RFR (M): 8059575: JEP-JDK-8043304: Test task: Tiered Compilation level transition tests

[Pavel Punegov]

Hi Tobias and Igor,

could you please review this: 
http://cr.openjdk.java.net/~ppunegov/8059575/webrev.05/

I replaced the check for OSR-methods to skip transitions after 
deoptimization as they may make intermittent failures.
See 67-70 lines at LevelTransitionTest.java

I will file a separate RFE to improve this test to be able to check 
transitions after deopt too.

Testing: jprt, locally
