cgraph.c (cgraph_update_edges_for_call_stmt_node): Added case when gimple call statement is update.

	* cgraph.c (cgraph_update_edges_for_call_stmt_node): Added case when
	gimple call statement is update.
	* gimple-fold.c (gimple_fold_call): Changed order for GIMPLE_ASSIGN and
	GIMPLE_CALL, where gsi iterator still points to GIMPLE CALL.
