	* tree-flow-inline.h (bsi_after_labels): Rewrite, return
	what its name says.
	* lambda-code.c (perfect_nestify): Use bsi_insert_before on
	bsi_after_labels iterator.
	* tree-if-conv.c (find_phi_replacement_condition,
	replace_phi_with_cond_modify_expr): Likewise.
	* tree-scalar-evolution.c (scev_const_prop): Likewise.
	* tree-ssa-loop-ivopts.c (compute_phi_arg_on_exit): Likewise.
