    c++: DWARF ICE with defaulted specialization [PR90674]

    Here when we merged the specialization with the implicit instantiation
    declaration, we wrongly kept the value of DECL_INITIALIZED_IN_CLASS_P f=

    the latter.

            * decl.c (duplicate_decls): Don't propagate
            DECL_INITIALIZED_IN_CLASS_P to a specialization.
