RFR(XS) 8199486: [Graal] gc/g1/ihop/TestIHOPStatic.java fails by timeout with -Xcomp

[Ekaterina Pavlova]

Hi All,

please review very simple change which disables running gc/g1/ihop/TestIHOPStatic.java
test in -Xcomp mode in case Graal is enabled. Running the test with Graal and -Xcomp causes
big heap contention by Graal and the test which results in slow test execution.

  webrev: http://cr.openjdk.java.net/~epavlova//8199486/webrev.00/index.html
testing: tested by running the test with different flags.

thanks,
