tree-dfa.c (find_vars_r): Do not call add_referenced_vars for globals. 

2012-05-29  Richard Guenther  <rguenther@suse.de>

	* tree-dfa.c (find_vars_r): Do not call add_referenced_vars
	for globals.
	(add_referenced_var_1): Re-organize.  Assert we are not
	called for globals.
	(remove_referenced_var): Likewise.
	* varpool.c (add_new_static_var): Use create_tmp_var_raw.
	* tree-mudflap.c (execute_mudflap_function_ops): Do not
	call add_referenced_var on globals.
	* matrix-reorg.c (transform_access_sites): Likewise.
