Revert of Speedup access to global_proxy.* attributes/accessors. (patchset #3 id:80001 of https://codereview.chromium.org/2403003002/ )

Original issue's description:
> Speedup access to global_proxy.* attributes/accessors.
>
> Using a global proxy (e.g. 'window.f', 'w.f' or 'this.f') is considerably slower than evaluating just 'f'. This CL aims to perform the necessary checks at compile time and inline the accesses.
>
> This is a follow-on CL to crrev.com/2369933005:
> - The initial upload is crrev.com/2369933005 + a rebase.
> - The remaining issues are the fixes requested by the reviewers on that CL.
