liftBinArith :: (Integer -> Integer -> Integer) -> BinArith BV

Turn a normal binop on Integers into one that can also deal with a bitsize. However, if the bitvector size is 0, always return the 0 bitvector.

liftDivArith :: (Integer -> Integer -> Integer) -> BinArith BV

Turn a normal binop on Integers into one that can also deal with a bitsize. Generate a thunk that throws a divide by 0 error when forced if the second argument is 0. However, if the bitvector size is 0, always return the 0 bitvector.
