Optimize `Sum` and `Counter` to avoid underflow/overflow logic when possible

[mkorbel1]

Motivation

As a follow-on to #89

It should be possible to avoid creating logic which considers whether an overflow/underflow has occurred by determining whether it is ever possible.

For example:

• If all interfaces are incrementing, and the initial value is not greater than the max (possible) value, then it cannot overflow
• If all interfaces are decrementing, and the initial value is not less than the min (possible) value, then it cannot underflow

Desired solution

Conditionally generate the portions of the If.block for overflow/underflow based on analysis of the provided interfaces.

Note that as part of this, we probably need to pass maxValue and minValue directly into Sum from Counter rather than the processed Logic versions of them, so that Sum can properly infer the true maximum/minimum values.
