pa.md (post_store, pre_load): New expanders.

        * pa.md (post_store, pre_load): New expanders.
        (post_stwm, pre_ldwm): Renamed to post_stw and pre_ldw respectively.
        (post_ldwm, pre_stwm): Make these unnamed patterns since we never
        need to directly generate RTL for them.
        * pa.c (hppa_expand_prologue, hppa_expand_epilogue): Corresponding
        changes.
