Please review: 8066185: VM crashed with SIGSEGV VirtualMemoryTracker::add_reserved_region

[Kumar Srinivasan]

Hello,

Please review the fix for the above issue.

Webrev:
http://cr.openjdk.java.net/~ksrini/8066185/webrev.00/

The fix is self explanatory, as for the test I have done the following:
a. refactored it from a single longish test to sub-tests for readability.
b. added new sub-test for NMT Argument Processing checks.

Thanks
Kumar
