        PR ipa/79337
        * ipa-prop.c (ipa_node_params_t::insert): Remove current
        implementation.
        (ipa_node_params_t::remove): Likewise.
        * ipa-prop.h (ipa_node_params::ipa_node_params): Make default
        initialization from removed ipa_node_params_t::insert.
        (ipa_node_params::~ipa_node_params): Move from removed
        ipa_node_params_t::release.
        * symbol-summary.h (symbol_summary::m_released): New member.
        Do not release a summary twice.  Do not allow to call finalizer
        for types of a summary that live in GGC memory.
