pa.c (legitimize_address): Consistently use Pmode rather than SImode.

Browse Source 
* pa.c (legitimize_address): Consistently use Pmode rather than
        SImode.  Do not call gen_pic2_highpart directly anymore.
        * pa.md (pic2_highpart): No longer a named pattern.
        (pic2_lo_sum): Similarly.  Reformat to make more readable.

needed.
