Oh man this took longer than I thought, and I had to juggle a lot of decisions ...

This is currently in a mergeable state, where the bulk of the work is done. Once merged, we'll be able to fix all the smaller issues one by one, instead of trying to fix everything altogether.

I turned off some of the previous optimizations, because they are interfering with each other. I also turned off some of the tests, because the optimizations aren't done yet.

In the next steps, I'll look into the bigger architecture first, mainly separate out the these interfering optimizations into separate ast passes.

During the meantime, you guys can pick up any commented out test and try to learn some JavaScript Grammar 😄

[Compare Source](https://togithub.com/oxc-project/oxc/compare/v0.1.0...821cc8e9c7cfb326ff546483bb2a32d12e018e4c)

Unfortunately, only the `json` format is supported right now.

The `extends` field will not take effect; normal `-D` and `-A` flags still apply.
