RFR(S): 8211124: HotSpot update for vm_version.cpp to recognise updated VS2017

[Kevin Walls]

Hi,

I'd like to get a review for a simple update to make hotspot aware of an 
additional Windows compiler version, for use in its long version info 
string (and in hs_err crash reports).

8211124: HotSpot update for vm_version.cpp to recognise updated VS2017
https://bugs.openjdk.java.net/browse/JDK-8211124

Thanks
Kevin
