Enable a handful of tests which require ES3.

Previously, these tests were commented out because Runtime Effects could
not compile ES3. More recently, the `enforceES2Restrictions` option flag
was added, which allows these tests to work inside a Runtime Effect.

Most of our commented-out tests can be supported this way; enabling them
a few at a time will make the inevitable debugging simpler when a driver
runs into issues with a test.
