a53781c8fd258608780821168a7f5faf7be63690 c++: don't predeclare std::type_info [PR48396]
We've always predeclared std::type_info, which has been wrong for a while,
but now with modules it becomes more of a practical problem, if we want to
declare it in the purview of a module. So don't predeclare it. For
building up the type_info information to write out with the vtable, we can
use void* instead of type_info*, since they already aren't the real types.
