Class fields, parser + byte code + test changes

I'm sending this because Xan is on holidays, but most of the Patch is an effort
from Xan and Caitp, with some fixes that I've made.

There is a case where the implementation is not passing the test (see below),
but we think it is ready for another batch of review.

```
{
  class C {
    x = Object.freeze(this);
    c = 42;
  }
  assertThrows(() => { new C; }, TypeError);
}
```
