	* cgraph.c (cgraph_release_function_body): Plug memory leak on
	ipa_transforms_to_apply and CFG; ggc_free gimple df and struct function
	so we are sure we do not dangle it forever.
	* function.c (outer_function_chain, find_function_data): Remove.
	(function_context_stack): New.
	(push_function_context, pop_function_context): Update.
	* function.h (struct function): Remove pointer outer.
	(outer_function_chain, find_function_data): Remove.
	* stmt.c (force_label_rtx): Remove dead call of find_function_data.
