Revert "[IRSim][IROutliner] Adding the extraction basics for the IROutliner."

Reverting commit due to address sanitizer errors.

> Extracting the similar regions is the first step in the IROutliner.
>
> Using the IRSimilarityIdentifier, we collect the SimilarityGroups and
> sort them by how many instructions will be removed.  Each
> IRSimilarityCandidate is used to define an OutlinableRegion.  Each
> region is ordered by their occurrence in the Module and the regions that
> are not compatible with previously outlined regions are discarded.
>
> Each region is then extracted with the CodeExtractor into its own
> function.

> We test that correctly extract in:
