pa.c (move_operand): Rely on memory_address_p to determine the validity of non-indexed memory addresses.

        * pa.c (move_operand): Rely on memory_address_p to determine the
        validity of non-indexed memory addresses.
        * pa.h (GO_IF_LEGITIMATE_ADDRESS): Allow LO_SUM with a symbolic
        operand in DFmode and SFmode when generating PA2.0 code.
