	PR tree-optimization/85964
	* tracer.c (better_p): Drop initialized count check, we only
	call the function with initialized counts now.
	(find_best_successor): Do find a best edge if one
	has uninitialized count.
	(find_best_predecessor): Likewise.  Do BB frequency check only
	if count is initialized.
