This is not yet part of any C++ working draft, and so is controlled by the flag -fchar8_t rather than a -std= flag. (The GCC implementation is controlled by a flag with the same name.) This implementation is experimental, and will be removed or revised substantially to match the proposal as it makes its way through the C++ committee. llvm-svn: 331244
