Subject: [PATCH] pa.md (movqi, [...]): Fix attributes which involve fp<->gr
 copies to match current reality.

        * pa.md (movqi, movhi, movsi, movdi, movsf, movdf): Fix attributes
        which involve fp<->gr copies to match current reality.
        (indexed loads): These should have "load" attributes, not "move".
