Having the matrix of test targets for incremental compilation in the individual test manifests has turned out to be inconvenient for a few reasons: the tests are almost certain to accidentally get out of sync, disabling targets entirely is annoying to do, and incr-check needs to take care to print the target in all error messages (which currently does not always happen). If I recall correctly, I originally designed it this way because it allows targets to be disabled at the granularity of individual tests, but there's an easier approach to that: just let a test manifest that it should be *skipped* on a certain target! As skipping is the rare case, and also the case you want readers to notice, it makes sense for *it* to be explicitly specified, like how unit tests use `error.SkipZigTest`. So, `incr-check` no longer runs through a list of targets specified in the manifest. Instead, it accepts (and, in fact, requires) a single target on the command line, and runs the test for that specific target. If the file contains a `#skip_target` directive for that target, then `incr-check` exits immediately, so we can still disable targets at individual test granularity, but you can also disable a target for all tests by just commenting it out of the matrix in `test/tests.zig`. As a nice bonus, this also allows the build system to run different incremental test targets in parallel, because the targets are now different steps. This definitely seems like a better way to split the work between the build system and incr-check---sorry for getting this wrong initially!
