Add free inline summary pass after pass_early_local_passes

	PR middle-end/53321
	PR middle-end/53865
	* ipa-inline-analysis.c (inline_free_summary): Return if
	inline_edge_summary_vec is NULL.

	* ipa-split.c (execute_split_functions): Check if a function
	is inlinable only if inline_edge_summary_vec != NULL.

	* ipa.c (symtab_remove_unreachable_nodes): Restore
	cgraph_propagate_frequency call when something was changed.
	(free_inline_summary): New function.
	(pass_ipa_free_inline_summary): New pass.

	* passes.c (init_optimization_passes): Add
	pass_ipa_free_inline_summary before pass_ipa_tree_profile.

	* timevar.def (TV_IPA_FREE_INLINE_SUMMARY): New.

	* tree-pass.h (pass_ipa_free_inline_summary): New.
