This makes scoverage work with incremental compilation. Instead of starting from scratch we reuse the data in `scoverage.coverage` for files that are not being compiled in this compilation unit (because zinc skipped them). We read the existing `scoverage.coverage` and merge it with the new one being generated. We make sure that statement ids by starting from the max id in the existing coverage. This PR also refactors the test code a little bit to be able to test for incremental compilation.
