Warnings should be fixed in vqm2blif

[vaughnbetz]

We should be warning clean, but vqm2blif isn't. See https://github.com/verilog-to-routing/vtr-verilog-to-routing/actions/runs/6333593038/job/17201935175 for a CI run that shows the warnings.

Expected Behaviour

No compiler warnings.

Current Behaviour

vqm2blif compiler warnings

@kimiatkh @Srivat97 : I am not sure who is the best person to fix these warnings (not sure if they are in the new hard block code or S10 code or something else) but it would be great if one of you could fix them.

[kimiatkh]

@vaughnbetz I can take care of that. Should be easy to fix. I think some of the warnings may be due to a recent compiler version upgrade, if there has been one.

[AlexandreSinger]

@kimiatkh I am currently working on removing all of the warnings in the VTR builds (see issue #2518 ). What is the progress on this issue?

[AlexandreSinger]

@vaughnbetz I think this issue can be closed since it was resolved in Navid's most recent PR. PR #2549
