RFR(XS) 8190975: Tests which run with "--limit-modules java.base" could fail when Graal is used as JIT

[Ekaterina Pavlova]

Hi all,

The following change fixes tests which run with "--limit-modules java.base" and as result could fail
in case they are run in Graal mode. The fix adds "jdk.internal.vm.compiler" module so Graal classes
can be loaded during Graal initialization.


    JBS:  https://bugs.openjdk.java.net/browse/JDK-8190975
webrev:  http://cr.openjdk.java.net/~epavlova//8190975/webrev.00/index.html

testing: Tested by running the tests in Graal as JIT compiler mode with -Xcomp flag.

Thanks,
