Summary:                    MSVC_VERSION is wrong
Description: 
In my setup I have installed VS 2010 through VS 2015 (except VS2012) and for
some reason when using the VS 2015 command line and the NMake generator the
value of MSVC_VERSION comes as 1800 instead of 1900. 

Also I have Intel Fortran 2013 and 2016 installed.

I have traced this issue to the file "Modules/Platform/windows-MSVC.cmake"
around line 62 where the variable MSVC_VERSION is set. 
The IF() statements fail except the Fortran one. And on that one
CMAKE_Fortran_SIMULATE_VERSION has a value of 18.0 and then this value is used.

It seems that this comes from Modules/CMakeFortranCompilerId.F.in.
I suggest that the Modules/CMakeFortranCompilerId.F.in gets updated. There is an
if statement where it checks for _MSC_VER >= 1800. The check for _MSC_VER >=
1900 should be added here for Visual Studio 2015 full support.
