Fix memory leaks in IPA.

	* ipa-inline-analysis.c (estimate_function_body_sizes): Call
	body_info release function.
	* ipa-prop.c (ipa_release_body_info): New function.
	(ipa_analyze_node): Call the function.
	(ipa_node_params::~ipa_node_params): Release known_csts.
	* ipa-prop.h (ipa_release_body_info): Declare.
