Add missing predicate to PREDICATE_CODES on PA

I changed reg_before_reload_operand to not accept SUBREG codes since
register_operand accepts them before reload.  They require an unwanted
reload.  The predicate codes for reg_before_reload_operand are now
REG and MEM.

Tested on hppa2.0w-hp-hpux11.11.

	* pa.c (reg_before_reload_operand): Don't accept a SUBREG operand.
	* pa.h (PREDICATE_CODES): Adjust codes for reg_before_reload_operand.
