    libstdc++: Fix outdated comment about standard integer types
    
    The long long and unsigned long long types have been standard since
    C++11, so are not extensions. There are also the char8_t, char16_t and
    char32_t types. Just refer to the standard integer types, without saying
    how many there are.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/cpp_type_traits.h: Fix outdated comment about the
            number of standard integer types.
