Log message:
	2004-01-20  Daniel Berlin  <dberlin@dberlin.org>
	
	* tree-alias-ander.c (andersen_op_assign): Update
	prototype. Make this handle &x in the operands using
	the addrargs parameter.
	(andersen_init): Turn off ip_partial until variables
	aliasing variables in other functions is resolved.
	(andersen_add_var): Use newly renamed alias_var_new_with_aterm.
	Fix comment.
	(andersen_add_var_same): Ditto.
	(andersen_function_call): Use ip_partial, not flag_unit_at_a_time.
	* tree-alias-common.c (get_values_from_constructor): Add bitmap
	and int * arguments. Used to mark operands that we are taking
	address of.
	(get_alias_var_decl): We should never see FIELD_DECL's right now.
	(intra_function_call): Reverse ordering for slightly faster
	projection merging.
	(find_op_of_decl): New function.
	(find_func_aliases): Use it.
	Comment x = foo.y case.
	Move get_alias_var_decl of arguments so we only call it if
	necessary.
	Handle address of arguments in operations.
	(create_fun_alias_var): tvar->var.
	Set context of fakeargs.
	Set context of fakedecls.
	Set DECL_PTA_ALIASVAR of RETURN_DECL's.
	(create_fun_alias_var_ptf): tvar->var.
	Set context of fakedecls.
	(create_alias_vars): Only create alias vars for globals
	with DECL_INITIAL's.
	* tree-alias-common.h (struct tree_alias_ops):
	Update op_assign arguments.
	(may_alias): Fix comment.
	(same_points_to_set): Ditto.
	(empty_points_to_set): Ditto.
	* tree-alias-type.h: Rename alias_tvar_new_with_aterm
	-> alias_var_new_with_aterm.
	* tree-alias-type.c: Ditto.
