	* ipa-prop.c (ipa_print_node_jump_functions): Print jump functions
	also for indirect edges.  Actual printing moved...
	(ipa_print_node_jump_functions_for_edge): ...here.
	(ipa_compute_jump_functions): Renamed to
	ipa_compute_jump_functions_for_edge and made static.
	(ipa_compute_jump_functions): New function.
	(make_edge_direct_to_target): Check if the number of arguments on
	the newly direct edge is the same as the number of parametrs of
	the callee.
	* ipa-cp.c (ipcp_init_stage): Most functionality moved to new
	ipa_compute_jump_functions.  Call ipa_analyze_params_uses.
	* ipa-inline.c (inline_indirect_intraprocedural_analysis): Call
	analysis functions unconditionally, call the new
	ipa_analyze_params_uses on the node instead of every edge.

	* testsuite/g++.dg/ipa/ivinline-8.C: New test.
	* testsuite/gcc.dg/ipa/iinline-2.c: New test.
