Modify Bool to only use 1 or 0, rater than last bit (#62)

Most methods of Bool currently rely on the last bit, but `CAS`
generates the int value to match `old` based on the user's input
and so it assumes the value is either `1` or `0`.

The only reason we relid on the last bit is that `Toggle` was
implemented using an atomic add. We can instead implement
`Toggle` using a loop around `CAS`.

Fixes #61.
