    of the internal procedure functions
    ShiftVal, ShiftLeft, ShiftRight, RotateVal,
    RotateLeft, RotateRight to handle large sets.
  * gm2/gm2-libs-coroutines/SYSTEM.mod: added implementation
    of the internal procedure functions
    ShiftVal, ShiftLeft, ShiftRight, RotateVal,
    RotateLeft, RotateRight to handle large sets.
  * gm2/gm2-compiler/M2GenGCC.mod:  fixed type change
    bug which occurred if a large bitset is compared to
    an empty set.  Use ConvertBinaryOperands for the
