https://bugs.openjdk.java.net/browse/JDK-8191788

This is redo of JDK-8190975 [1] fix which added jdk.internal.vm.compiler to tests which have 
--limit-modules option. Unfortunately tests start failing on SPARC where Graal 
(jdk.internal.vm.compiler) is not available. JDK-8191653 [2] reversed 8190975 changes to fix that 
problem.

This fix adds jdk.internal.vm.compiler to --limit-modules list in JVM only when Graal is used: when 
it is explicitly specified with -Djvmci.Compiler=graal or in default case and when UseJVMCICompiler 
is true.

I tested the fix with failed tests from JDK-8190975 which are mostly AppCDS tests in 
test/runtime/appcds/jigsaw and also test/jdk/java/lang/String/concat/WithSecurityManager.java

I think this fix may break upgradeable status of Graal (for Oracle Labs version of Graal).
But it should be fine since it is only used with --limit-modules which is not used by Labs.

Thanks,
Vladimir
