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. llvm-svn: 248064 2015-09-19 07:18:39 +08:00			`// RUN: %clang_cc1 -fsyntax-only -std=c++11 -verify %s -Wc++14-binary-literal`
