Almost having working Verilator. One issue in the testbench remains.

Created by: rosethompson

• More progress towards verilator.
• Kind of a frustrating set of changes to get the verilator errors out of the copyShadow module.
• Closer to verilator support.
• functionName.sv is now linting for rv64gc.
• Cleanup. Verilator still has issues with riscassertions.sv and the testbench
• Yay! I got verilator to compile our testbench! Does it actually work I don't know.
• Restored the one hack change which prevents verilator from working.
