Use many more valid test cases (#10640)
Use many more valid test cases (#10640)

There are over 500 test cases in `select_cases.txt` that are all invalid
because it uses `select from`. This is more likely a mistake, since the
queries are valid if this is changed to `select * from`.

Moving this exercises more valid queries and improves test coverage.
Having 500+ cases that all test the exact same parse error isn't useful
so I think this change is a net improvement.
