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".
