[8022452] Hotspot needs to know about Windows 8.1 and Windows Server 2012 R2

[Miroslaw Niemiec]

Hello!

I'd like to ask for review and approval for a direct back port from 8 to 7

Can I ask to expedite the review since

changes in
void os::win32::print_windows_version(outputStream* st)
applied with _no modification_  to jdk7

and there is no difference in
os::win32::print_windows_version()
between jdk8 and jdk7

This fix also needs to be done to complete a fix
for another CR: JDK-8020191
System.getProperty( " os.name " ) returns " Windows NT (unknown) " on 
Windows 8.1


This CR:
https://bugs.openjdk.java.net/browse/JDK-8022452

webrev for 7 (I am asking for review and approval):

Thank you
