Revert of Deactivate Parser Bookmarks

Revert of Deactivate Parser Bookmarks (patchset #1 id:1 of https://codereview.chromium.org/1315173007/ )

Reason for revert:
Tanks performance (Mandreel latency). A simple deactivation will not work.

Original issue's description:
> Deactivate Parser Bookmarks.
>
> Bookmarks may create a race condition which
> results in syntax errors. The more files are parsed
> in parallel the higher the probability that the error
> occurs.
> Unfortunately it is not possible to simply revert the
> CLs related to Bookmarks.
