hppa: Fix LO_SUM DLTIND14R address support in PRINT_OPERAND_ADDRESS 

This bug was hidden since LO_SUM DLTIND14R addresses are normally
handled by the A constraint in the move patterns.

2024-03-23  John David Anglin  <danglin@gcc.gnu.org>

gcc/ChangeLog:

	* config/pa/pa.cc (pa_output_global_address): Handle
	UNSPEC_DLTIND14R addresses.
	* config/pa/pa.h (PRINT_OPERAND_ADDRESS): Output "RT'" for
	UNSPEC_DLTIND14R address.
