    c++: Fix printing of decltype(nullptr) [PR97517]

    The C++ printer doesn't handle NULLPTR_TYPE, so we issue the ugly
    "'nullptr_type' not supported by...".  Since NULLPTR_TYPE is
    decltype(nullptr), it seemed reasonable to handle it where we
    handle DECLTYPE_TYPE, that is, in the simple-type-specifier handler.
