Features: Enable writing of MSVC compiler feature header.
Notes: VS2015 and above are the only MSVC versions to support cxx_final, so remove usages from the tests, and instead only test for cxx_override. VS2012 and above to conform to cxx_decltype_incomplete_return_types proposal, but without support for auto return types the dcl.type.simple example in the proposal doesn't compile. VS2013 and above to conform to the updated cxx_contextual_conversions proposal, but VS2010 and above pass the test. Compilers such as MSVC have no explicit flags to enable C++11 mode, it just is always on. So only run the link tests with compilers that require a flag to specify the language version.
