Christopher Chedeau cf45afba61 Add testing
- This brings in the flow test suite that contains a ton of JavaScript parsing edge cases
- This creates snapshot tests using the pretty printer for all of them
- If uncomment `RUN_AST_TESTS` line in `tests/run_specs.js`, it checks ast(pretty_print(x)) == ast(x). Right now, "178 failed, 197 passed, 375 of 377 total". So half of the tests are not passing, most of them are crashes and many of the rest are subtle issues.

/**
* I've hit a bug with the caching in flow_js.ml. Avik is removing that caching
* so it should be fixed soon. The basic idea is I flow something like
*
* Array<any | any> ~> Iterable<string>
*
* then Flow won't notice when I try to flow
*
* Array<string | number> ~> Iterable<string>
*
* We shouldn't hit the cache because the union types are different, but we do
* anyway. I've fixed this temporarily by bumping the "meaningful" param to
* Hashtbl.hash_param
