Declare overloads discriminating on whether the OUString is lvalue (&) 
or rvalue (&&).

(Which, alas, is no panacea if forming a string_view over the temporary 
OUString would be fine because the string_view temporary doesn't outlive 
the full expression either.  That is, you would like

   getSomeOUString().getToken(...).toInt32()

to use the string_view variant after all.)
