	(ipa_get_cs_argument_count): Updated to work on vectors.
	(ipa_get_ith_jump_func): Likewise.
	* ipa-prop.c (ipa_count_arguments): Removed.
	(compute_scalar_jump_functions): Use ipa_get_ith_jump_func to access

	(compute_pass_through_member_ptrs): Likewise.
	(compute_cst_member_ptr_arguments): Likewise.
	(ipa_compute_jump_functions_for_edge): Get number of arguments from
	the statement, allocate vector.
