	(do_estimate_edge_size): Likewise.
	(do_estimate_edge_hints): Likewise.
	* ipa-inline.c (reset_edge_caches): Likewise.
	(recursive_inlining): Likewise.
	(inline_small_functions): Likewise.
	* ipa-inline.h (initialize_growth_caches): Remove.
	(estimate_edge_size): Likewise.
	(estimate_edge_time): Likewise.
	(estimate_edge_hints): Likewise.
	(reset_edge_growth_cache): Likewise.
	* symbol-summary.h (call_summary::remove): New method.
