This uses go/parser and go/ast to analyze all test files in ~1 second. It only recognizes a few simple structures that the tests all have, and modifies a few tests to fit expected structure better. This is part of an effort to ensure all tests have owners, by having a verify check to catch new tests being added without an owner.
