boost.config defines BOOST_NO_CXX11_USER_DEFINED_LITERALS but I believe
this defect macro could not be used for detecting chrono literals support.

Should the new BOOST_NO_CXX14_CHRONO_LITERALS depend on the compiler or
stdlib version?
AFAIK chrono literals are available since gcc-4.9.3 (clang?, intel?, msvc?).
