[9] review request: 8155692: changes to compile under Visual Studio 14.0

[Jim Graham]

Bug: https://bugs.openjdk.java.net/browse/JDK-8155692
webrev: http://cr.openjdk.java.net/~flar/JDK-8155692/webrev.00/

It's mostly just a build file change to pick up the compilers from the 
new VS140COMNTOOLS location, but it also includes a change to minimize 
the impact of a recent change to throw an error on the deprecation of 
hash_map and hash_set.  I briefly looked at upgrading GlassClipboard.cpp 
to the preferred unordered_map and unordered_set classes, but the hash 
functions weren't compatible in a way that wasn't trivial to sort out. 
We should probably upgrade to the more standard collections classes.  I 
can file a follow-on bug for that if we decide to go with the #define 
IGNORE fix here...
