Investigate performance to get const time gas cost lookups

[ControlCplusControlV]

    lazy_static alone may be insufficient, would require some investigation to find the exact solution. But agree that an issue would be a good way to resolve this for now.

i.e. Our gas costs are behind an Arc, so every lookup might add up over time. Inside the VM, we could consider doing a clone or ref instead of doing an Arc lookup every time.

Need to do more investigation. We should just do some simple benchmarking/flamegraphing to analyze the differences between Arc and some other solution.
