Fix memory leaks in IPA CP (PR ipa/79337).
2017-02-03 Martin Liska <mliska@suse.cz>
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.
