    PowerPC: modf optimization fix
    
    This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits
    by correctly setting minimum architecture for modf PPC optimization
    to power5+ instead of power5 (since only on power5+ round/ceil will
    be inline to inline assembly).

    PowerPC: modf optimization
    
    This patch implements modf/modff optimization for POWER by focus
    on FP operations instead of relying in integer ones.
