Hyeon-bin Jeong: libc++ fails to create any classes inherit from basic_ios if they provided char type other than char or wchar_t. It throw exception during construction, so there is no chance to imbue own ctype. This fixes http://llvm.org/bugs/show_bug.cgi?id=13698 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@162648 91177308-0d34-0410-b5e6-96231b3b80d8
