I want to use Z for multi-letter constraints.  So first we have to

adjust the existing use of Z.  This does not affect code generation.


Pushed to the trunk,

    Rename "z" constraint to "Zz" on the H8/300
    
    I want to use Z as a multi-letter constraint.  So first we have to
    adjust the existing use of Z.  This does not affect code generation.
    
    gcc/
            * config/h8300/constraints.md (Zz constraint): Renamed
            from "z".
            * config/h8300/movepush.md (movqi_h8sx, movhi_h8sx): Adjust
            constraint to use Zz instead of Z.
