Investigate Bits instance on Array CBool

Theoretically, there's no reason this can't be supported.

```haskell
instance Bits (ArrayFire CBool) where
(.&.) = A.and
(.|.) = A.or
xor = A.bitXor
shiftL x n = A.shiftL x (scalar n)
shiftR x n = A.shiftR x (scalar n)
```

Still need to look into implementing the following:
```haskell
(rotate | rotateL, rotateR), bitSize, bitSizeMaybe, isSigned, testBit, bit, popCount
```
