[tree-inline][obvious] Delete redundant count_insns_seq

	* tree-inline.h (count_insns_seq): Delete prototype.
	(estimate_num_insns_seq): Define prototype.
	* tree-inline.c (count_insns_seq): Delete.
	(estimate_num_insns_seq): Remove static qualifier.
	* tree-eh.c (decide_copy_try_finally): Replace use of count_insns_seq
	with estimate_num_insns_seq.
