Get default -fms-compatibility-version from cl.exe's version
-fms-compatibility-version was defaulting to 18 (VS 2013), which is a pain if your environment is pointing to version 19 (VS 2015) libraries.
If cl.exe can be found, this patch uses its version number as the default instead. It re-uses the existing code to find the Visual Studio binaries folder and WinAPI methods to check its version. You can still explicitly specify a compatibility version on the command line. If you don't have cl.exe, this should be a no-op and you'll get the old default of 18.
This affected the tests, which assumed that if you didn't specific a version, that it would default to 18, but this won't be true for all machines. So a couple test cases had to be eliminated and a couple others had to be tweaked to allow for various outputs.
