Robert Maynard f73718c9b8 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.

Stephen Kelly c13656e717 Features: Test nullptr as a side-effect activation of static_assert.
Because not all compilers under test support the existing 'activation
features', add another test to ensure that compilers which support
both static_assert and nullptr behave as expected in this test.

Stephen Kelly b3e86f4e97 Features: Test an expectation of whether OVERRIDE_CONTROL is expected
The tests below test the presence of both cxx_final and cxx_override,
only one of which is supported by MSVC.  The test is in part intended
to verify that the COMPILE_FEATURES genex supports multiple arguments
and allows users to define names for groups of features (Clang already
calls cxx_final and cxx_override 'override control' as a group).  Keep
the test, and allow the expectation to be set as appropriate.

Stephen Kelly 0dfe395e3c Features: Add COMPILE_FEATURES generator expression.
Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.
