Bug: https://bugs.openjdk.java.net/browse/JDK-8170307 (not public)

This change removes an ancient workaround that limited the usable stack 
of the primordial process thread to 2MB. This only affects applications 
that use the JNI invocation API to load the VM in the primordial process 
thread. The stack size will now be controlled by the -Xss stack option 
and the OS limit (specified through rlimit). In the corner case where no 
Java stack size is specified and rlimit is unlimited, then we impose a 
8MB limit as done on Solaris.

8u webrev: http://cr.openjdk.java.net/~dholmes/8170307/webrev.8u/

As the patch did not apply directly due to the amount of change in the 
file in JDK 9 I had it re-reviewed here:
