Research direction

Start with LLVM PR 168390 and trace the verification changes affecting CalyxCell and CalyxPrimitive. Find where CalyxCell instances are marked as symbols and compare that behavior with the verifier's expectations. Done means the affected Calyx instances no longer trigger the upcoming verification failure.
