C++: Simplify boundFromGuard
...
The last disjunct in `boundFromGuard` is moved into `linearBoundFromGuard`. This avoids repeating the calculation for `boundValue`.
`getBounds` and `getExprTypeBounds` are turned into predicates with result. Their middle argument was the "output" which was confusing.

C++: Use or instead of if
...
The proposition in the true branch implied the condition, so `or` is more appropriate. Also eliminated an existentially quantified variable.
