* v850-opc.c (v850_operands): D6 -> DS7. References changed.

        Add D8 for 8-bit unsigned field in short load/store insns.
        (IF4A, IF4D): These both need two registers.
        (IF4C, IF4D): Define.  Use 8-bit unsigned field.
        (v850_opcodes): For "sld.h", "sld.w", "sst.h", "sst.w", use
        IF4C & IF4D.  For "trap" use I5U, not I5.  Add IF1 operand
        for "ldsr" and "stsr".
        * v850-opc.c (v850_operands): 3-bit immediate for bit insns
        is unsigned.
Fixing up the parser again.
