Instead of using `zig test` to build a special version of the compiler that runs all the test-cases, the zig build system is now used as much as possible - all with the basic steps found in the standard library. For incremental compilation tests (the ones that look like foo.0.zig, foo.1.zig, foo.2.zig, etc.), a special version of the compiler is compiled into a utility executable called "check-case" which checks exactly one sequence of incremental updates in an independent subprocess. Previously, all incremental and non-incremental test cases were done in the same test runner process. The compile error checking code is now simpler, but also a bit rudimentary, and so it additionally makes sure that the actual compile errors do not include *extra* messages, and it makes sure that the actual compile errors output in the same order as expected. It is also based on the "ends-with" property of each line rather than the previous logic, which frankly I didn't want to touch with a ten-meter pole. The compile error test cases have been updated to pass in light of these differences. Previously, 'error' mode with 0 compile errors was used to shoehorn in a different kind of test-case - one that only checks if a piece of code compiles without errors. Now there is a 'compile' mode of test-cases, and 'error' must be only used when there are greater than 0 errors. link test cases are updated to omit the target object format argument when calling checkObject since that is no longer needed. The test/stage2 directory is removed; the 2 files within are moved to be directly in the test/ directory.
