Some of them would be nice to have, in any case. e.g. The absence of
BOOST_NO_CXX14_VARIABLE_TEMPLATES would enable a library author to
provide things like _v value traits [conditionally, for those who only
care about C++14 and want to use them, or just for consistency with
the C++ standard library that now provides them].

I think these ones are reasonable:
- BOOST_NO_CXX14_DECLTYPE_AUTO
- BOOST_NO_CXX14_VARIABLE_TEMPLATES
- BOOST_NO_CXX14_GENERIC_LAMBDAS
- BOOST_NO_CXX14_BINARY_LITERALS
- BOOST_NO_CXX14_DEPRECATED_ATTRIBUTES

And this one after renaming slightly:
- BOOST_NO_CXX14_RELAXED_CONSTEXPR

And this one instead, for lambda capture:
- BOOST_NO_CXX14_LAMBDA_CAPTURE_EXPRESSIONS
(Or perhaps not, if it's too lengthy)

I'll put aside some time to look at the tests; I haven't reviewed them yet.
