as floats.
      * tic80-opc.c (SPFI): Add single precision floating point
      immediate operand type.
      (ROTATE): Add rotate operand type for shifts.
      (ENDMASK): Add for shifts.
      (n): Macro for the 'n' bit.
      (i): Macro for the 'i' bit.
      (PD): Macro for the 'PD' field.
      (P2): Macro for the 'P2' field.
      (P1): Macro for the 'P1' field.
      (tic80_operands): Add entries for "exts", "extu", "fadd",
      "fcmp", and "fdiv".
