Andrew Kelley 66f3efb63b migrate runtime safety tests to the new test harness
* migrate runtime safety tests to the new test harness
   - this required adding compare output / execution support for stage1
     to the test harness.
 * rename `zig build test-stage2` to `zig build test-cases` since it now
   does quite a bit of stage1 testing actually. I named it this way
   since the main directory in the source tree associated with these
   tests is "test/cases/".
 * add some documentation for the test manifest format.
