[8u] RFR(xS): 8209359: [8u] hotspot needs to recognise cl.exe 19.13 to build with VS2017.

[Kevin Walls]

Hi,

I'd like to get a review of this small change to let the jdk8u/hotspot 
build system recognise another Microsoft compiler version:

8209359: [8u] hotspot needs to recognise cl.exe 19.13 to build with VS2017.
https://bugs.openjdk.java.net/browse/JDK-8209359

Diff below, just another if following the same pattern.

Thanks
Kevin
