Eric Fiselier	49e2967f27	[libc++] Fix and document visibility attributes for Clang, GCC and Windows. Summary: This patch fixes a number of problems with the visibility macros across GCC (on Unix) and Windows (DLL import/export semantics). All of the visibility macros are now documented under `DesignDocs/VisibilityMacros.rst`. Now I'll no longer forget the subtleties of each! This patch adds two new visibility macros: * `_LIBCPP_ENUM_VIS` for controlling the typeinfo of enum types. Only Clang supports this. * `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` for redefining visibility on explicit instantiation declarations. Clang and Windows require this. After applying this patch GCC only emits one -Wattribute warning opposed to 30+.
