Upgraded from Babel 6 to Babel 7.
The only significant change seems to be the way `@babel/plugin-transform-classes` handles classes differently from `babel-plugin-transform-es2015-classes`. In regular mode, the former injects a `_createClass` function that increases the bundle size, and in the latter it removes the safeguard checks. However, this is okay because we don't all classes in new features, and we want to deprecate class usage in the future in the react repo.

* Add command to run tests in persistent mode
* Convert Suspense fuzz tester to use noop renderer
So we can run it in persistent mode, too.
* Don't mutate stateNode in appendAllChildren
We can't mutate the stateNode in appendAllChildren because the children
could be current.
This is a bit weird because now the child that we append is different
from the one on the fiber stateNode. I think this makes conceptual
sense, but I suspect this likely breaks an assumption in Fabric.
With this approach, we no longer need to clone to unhide the children,
so I removed those host config methods.
Fixes bug surfaced by fuzz tester. (The test case that failed was the
one that's already hard coded.)
* In persistent mode, disable test that reads a ref
Refs behave differently in persistent mode. I added a TODO to write
a persistent mode version of this test.
* Run persistent mode tests in CI
* test-persistent should skip files without noop
If a file doesn't reference react-noop-renderer, we shouldn't bother
running it in persistent mode, since the results will be identical to
the normal test run.
* Remove module constructor from placeholder tests
We don't need this now that we have the ability to run any test file in
either mutation or persistent mode.
* Revert "test-persistent should skip files without noop"
Seb objected to adding shelljs as a dep and I'm too lazy to worry about
Windows support so whatever I'll just revert this.
* Delete duplicate file
