RFR 8217846: [Graal] vmTestbase/nsk/jdi/VirtualMachine/instanceCounts/instancecounts003/instancecounts003.java crash

[Harold Seigel]

Hi,

Please review this fix for JDK-8217846.  The fix adds array classes to 
their classLoaderData list after creating the class's mirror because if 
mirror creation fails (perhaps because of an OOME) then the class should 
not be added to its classLoaderData list.

Open Webrev: http://cr.openjdk.java.net/~hseigel/bug_8217846/webrev/

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8217846

The fix was tested by running the test over 1000 times.

The fix was regression tested by running Mach5 tiers 1 and 2 tests and 
builds on Linux-x64, Solaris, Windows, and Mac OS X and by running Mach5 
tiers 3-7 tests on Linux-x64.

Thanks, Harold
