	* ipa-prop.h (enum jump_func_type): New value IPA_JF_ANCESTOR, changed
	comments.
	(struct ipa_pass_through_data): New type.
	(struct ipa_ancestor_jf_data): New type.
	(union jump_func_value): Removed field formal_id, added fields
	pass_through and ancestor.
	(struct ipa_param_call_note): Changed type of formal_id to int from
	unsigned.
	* ipa-prop.c (ipa_print_node_jump_functions): Print pass through with
	operations jump functions and ancestor jump functions.
	(compute_complex_pass_through): New function.
	(compute_scalar_jump_functions): Call compute_complex_pass_through,
	reflect changes in the jump function strucutre.
	(update_jump_functions_after_inlining): Ignore complex pass-through
	and ancestor jump functions.
	* ipa-cp.c (ipcp_lattice_from_jfunc): Added support for ancestor and
	polynomial pass-through with operation jump functions.
