[11] RFR(XS): 8200227: [Graal] Test times out with Graal due to low compile threshold

[Tobias Hartmann]

Hi,

please review the following test patch:
https://bugs.openjdk.java.net/browse/JDK-8200227
http://cr.openjdk.java.net/~thartmann/8200227/webrev.00/

The test times out with Graal as JIT because it sets -Xbatch -XX:-TieredCompilation
-XX:CompileThreshold=100 which extremely slows down execution due to many blocking compilations of
Graal internal code that needs to be compiled by Graal itself. The test should be executed with
TieredCompilation enabled to allow Graal code to be C1 compiled. I've verified that all intrinsified
methods are still compiled (i.e., the test still does what it's supposed to do).

I've also searched for other tests that use the same flag combination but we don't have any.

Thanks,
Tobias
