        * sparc.md (abstf2): This should be an expand.
        (split after abstf2_notv9): Fix mode.
        (abstf2_hq_v9): New pattern.
        (abstf2_v9): Only use when no hard quad.
        (absdf2_v9): Fix if target is not the same as source.
        (ashrsi3_extend, ashrsi3_extend2, lshrsi3_extend, lshrsi3_extend2):
        Add correct output constraints.
