gimple-fold.c (gimple_fold_call): Use gimple_call_noreturn_p instead of testing ECF_NORETURN bit in gimple_call_flags. 

* gimple-fold.c (gimple_fold_call): Use gimple_call_noreturn_p
	instead of testing ECF_NORETURN bit in gimple_call_flags.
	* tree-cfg.c (make_edges_bb, execute_fixup_cfg): Likewise.
	* predict.c (tree_bb_level_predictions): Likewise.
	* gimple-low.c (gimple_stmt_may_fallthru): Likewise.
