Request for review: JDK-8032970: stack size check methods for WhiteBox API

[Vitaly Davidovich]

Also this bit should be using rss in L72-73

System.out.print("Remaining stack size " + rss + ": ");
  72         if ( fss < sso * 0.8 || fss > sso * 1.2 ) {
  73             throw new RuntimeException("getThreadRemainingStackSize
value [" + fss + "] should be within 80%..120% of the value returned by
HotSpotDiagnosticMXBean");
  74         } else {
  75             System.out.println("OK");
  76         }
