* Gets an expression that equals this bound plus `delta`.
* Gets an expression that equals this bound plus `delta`. For example given
* the expression `x = foo() + 1` the variable `x` has a bound with
* expression `call to foo()` and delta `-1`.
*
* For the zero-bound this gets integer constants equal to `delta`, and for
* other bounds this gets expressions equal to the bound while `delta = 0`.
