Log message:
	2003-10-14  Daniel Berlin  <dberlin@dberlin.org>
	
	* tree-alias-ander.c (throwaway_global): Delete.
	(andersen_same_ponts_to_set): We handle all globals individually
	now.
	* tree-alias-common.c:  Remove doxygen markers.
	(get_alias_var_decl): Always create an alias var for globals now.
	Assign the global alias vars to GLOBAL_VAR, too.
	(intra_function_call): Fix logic, do a bit of pre-filtering to
	avoid useless global aliasing.
	(get_values_from_constructor): It's the same for field based and
	not field based.
	(create_alias_vars): Remove special global var handling.
	(same_points_to_set): Ditto.
	(ptr_may_alias_var): Ditto.
