Revert of Added orphaned compiled Python file checks. (patchset #2 id:20001 of https://codereview.chromium.org/621533002/)

Reason for revert:

Original issue's description:
> Added orphaned compiled Python file checks.
> 
> There have been a handful of cases where orphaned compiled Python files (.pyc
> files without an accompanying .py file) have been loaded preferentially by
> the presubmit scripts, causing weird problems. This adds a check and a mode for
> such files, either warning the user or deleting them.
> 
> BUG=None
> TEST=local
>   - Tested against local repository.
