libsolidity/codegen: Use calldatacopy to cheaply zero memory instead of
...
codecopy.
Motiviation:
Zero'ing memory is commonplace in contracts, but with the upcoming
Layer-2 EVM translation layers and other on-chain verification
mechanisms, using `codecopy` becomes a `costly` operation in those
sandboxes. Using `calldatacopy` achieves the same thing, gas costs
are also the same as codecopy, and is significantly cheaper in the `sandbox` situation.
