	(enum ipa_lattice_type): Moved down in the file.
	(struct ipa_param_descriptor): New field polymorphic.
	(ipa_is_param_polymorphic): New function.
	* ipa-prop.c: Include gimple.h and gimple-fold.h.
	(ipa_print_node_jump_functions): Print known type jump functions.
	(compute_complex_pass_through): Renamed to...
	(compute_complex_assign_jump_func): this.
	(compute_complex_ancestor_jump_func): New function.
	(compute_known_type_jump_func): Likewise.
	(compute_scalar_jump_functions): Create known type and complex ancestor
	jump functions.

	(update_call_notes_after_inlining): Renamed to...
	(update_indirect_edges_after_inlining): this.  Moved edge creation for
	indirect calls to try_make_edge_direct_simple_call, also calls
	try_make_edge_direct_virtual_call for virtual calls.
	(ipa_print_node_params): Changed the header message.
	(ipa_write_jump_function): Stream also known type jump functions.
