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).

Because in the real semantics CFRelease can be used more than once, and also the variables can be used after CFRelease in general, modelling this as `free` causes many `USE_AFTER_FREE` errors. Now we change the model to not add the `Invalid CFree` attribute, but to just remove the `Allocated` attribute. So we can model memory leaks in the simple case of `Create` and not `CFRelease` before going out of scope, but we avoid the `USE_AFTER_FREE`.
Since the model for CFRelease now diverges from free, changed the command line option for modelling to `pulse-model-release-pattern`.
