        gimple_stmt_iterator with a gimple_phi_iterator, using it to make
        local "phi" be a gimple_phi.

        (single_non_singleton_phi_for_edges): Return a gimple_phi; update
        local to be a gimple_phi, adding checked casts since we're working
        on a sequence of gimple_phi.
        (conditional_replacement): Require a gimple_phi.

OK once prerequisites go in.
