Split off the binary literal warning into a subgroup of C++14 warnings
Binary literals predate C++14, but they are listed as a C++14 extension since
this was the first time they were standardized in the language. Move the
warning into a subgroup so it can be selectively disabled when checking for
other C++14 features.
