Simon Lydell dc93bdc983 Sync the Flow tests (#1163)
* Extract custom tests from tests/flow/

Approach:

1. Remove all .js files in tests/flow except .snap.js files.
2. Copy over all .js files from tests/ in the flow repo.
3. Go through the diff looking for deletions.
   - It was easy to see which deletions were due to changes in the tests
     due to updates in the flow repo.
   - For the rest of the deletions, I used `git blame` to verify that
     they had been added by us since the flow tests were copied over.

This makes tests/flow/ simply a copy of the tests from the flow repo,
making it easier to sync with the upstream flow tests in the future.

* Add a script for syncing the flow tests
