The addition of AOT support (JDK-8172670) for Windows in JDK 10 requires a Visual Studio Installation in order to run the Jtreg AOT tests.

The jaotc tool will attempt to execute "link.exe" from the default Windows installation directory. It will search for VS2012, VS2013 or VS2015. If link.exe is not found in any of these installations, the tests will fail.

The AOT support for Windows was integrated without jtreg support on windows due to the lack of JPRT support. This issue is corrected with this changes in addition to the re-enabling of the jtreg tests.
