Some embedded platforms do not wish to support the C library functionality for handling wchar_t because they have no use for it. It makes sense for libc++ to work properly on those platforms, so this commit adds a carve-out of functionality for wchar_t. Unfortunately, unlike some other carve-outs (e.g. random device), this patch touches several parts of the library. However, despite the wide impact of this patch, I still think it is important to support this configuration since it makes it much simpler to port libc++ to some embedded platforms.
