Maybe not for this commit, but should rather expose the `m_ConstantInt` functionality to C API somehow and drop the dependency on the arith dialect here. There are other constant-like operations that we may want to support, and ConstantOp may be defining a floating-point value or a vector that we don't want to support here.
