JDK-8063096 - Need tests to check that trivial methods are always compiled with C1
Description
Verify that level transition is correct. There are several "legal" queues like C0 -> C3 -> C4 which should be verified for methods and OSR.
Comments
Attached test 'Simple.java' that triggers compilation of all possible trivial constant getter methods (as defined by the fix for JDK-8056071). The final test should then check if all trivial methods are compiled with C1.

We should also add tests to verify that 'trivial' methods are always compiled with C1 in TieredCompilation mode (see JDK-8063096 and JDK-8056071).

Putting defer label on this so we can review the deferral.

It's too late for new tests. These needs to be deferred to 8u20 so please follow the deferral process.
