Summary: We do not use an arbitrary threshold to test cost results anymore but instead rely on `cost-issues` which do not have any trace attached. This diff adds traces to `costs-report.json` so that we can test cost issues with traces.

Summary:
The model returns an array the length of which is the same to that of enum entries.
It takes the length of enum entries from the summary of `Enum.values` because it is not written in `tenv`. In order to do that, the model semantics should be able to request the summary of the function with `get_summary`, so I extended `model_env` to include the functionality.

Summary:
In order to test cost analysis results, currently we rely on having an arbitrary cost threshold (200) and report issues that exceed this cost. For instance, a cost of 201 is considered expensive and reported as `EXPENSIVE_EXECUTION_TIME` issue in cost tests.
This means, if we change the cost analysis in a slight way that results in some constant cost increase under 200, we wouldn't able to detect it. I find this unsatisfactory and somewhat hacky.
This diff adds the ability to write the result of `costs-report.json` into a separate `cost-issues.exp` and then compare the actual costs (not only than relying on this arbitrary threshold reporting mechanism).
