Switch from unified table to range_op_table. There can be only one.

Now that there is only a single range_op_table, make the base table the
only table.

	* range-op.cc (unified_table): Delete.
	(range_op_table operator_table): Instantiate.
	(range_op_table::range_op_table): Rename from unified_table.
	(range_op_handler::range_op_handler): Use range_op_table.
	* range-op.h (range_op_table::operator []): Inline.
	(range_op_table::set): Inline.
