Description
This is a primitive Property operation, defined by FIRRTL spec section 25.1.1. General folds for signed arbitrary precision integer arithmetic can be applied, but none were defined in the initial PR. This could include things like:
- integer_add(a, 0) -> a
- integer_add(constantA, constantB) -> constantA + constantB
- etc...

Research direction
Start with FIRRTL specification section 25.1.1 and the existing IntegerAddOp implementation from the initial PR. Identify how primitive property operations currently fold, then cover the listed zero-identity and constant-constant cases. Done means the requested arithmetic folds are implemented and their results are validated.
