RFR (XS) 8229134: [TESTBUG] 32-bit build fails gc/arguments/TestSurvivorAlignmentInBytesOption.java after JDK-8228855

[Aleksey Shipilev]

Testbug:
  https://bugs.openjdk.java.net/browse/JDK-8229134

ObjectAlignmentInBytes is not available on 32-bit VMs. So the fix it to check for that before trying:
  http://cr.openjdk.java.net/~shade/8229134/webrev.01/

Testing: affected tests on x86_32, x86_64
