[PATCH] Introducing initial UseAuto transform

[Edwin Vane]

  I was mainly hoping for some sort of established pattern to emulate.

  The one issue I've been fighting with is where to put the auto-generated tests. I originally wanted them to live in the build directory but lit doesn't consider them part of the test suite it discovers in the source directory. I had wanted the auto-generated tests to behave just like hand-written tests that live in the source directory. To achieve this the files would need to be auto-generated into the source tree. So which is more preferable: polluting the source tree with files generated by the build or treating auto-generated files as a separate test suite in the build directory?
