Test and support all cpp operator types.

2010-06-07  Sami Wagiaalla  <swagiaal@redhat.com>

	* value.h: Created oload_search_type enum.
	(find_overload_match): Use oload_search_type enum.
	* valops.c (find_overload_match): Support combined member and
	non-member search.
	* eval.c (evaluate_subexp_standard): Calls to
	find_overload_match now use oload_search_type enum.
	(oload_method_static): Verify index is a proper value.
	* valarith.c (value_user_defined_cpp_op): Search for and handle
	both member and non-member operators.
	(value_user_defined_cpp_op): New function.
	(value_user_defined_op): New function.
	(value_x_unop): Use value_user_defined_op.
	(value_x_binop): Ditto.
	* cp-support.c (make_symbol_overload_list_using): Added block
	iteration.
	Add check for namespace aliases and imported declarations.
