Improve test coverage (#384)

* Report coverage for almost all jobs
  * Some jobs fail and are omitted
* Add more tests to `gen_tile_test.cpp`
  * Also lightly cleaned up formatting
* Clean up cmake/* files
  * So they don't report an empty version
* Remove commented `check_*` lines from `CMakeLists.txt` file
  * These were left over from the initial CMake support implementation
