Tobias Grosser ef6ae7030d ScopDetection: Make enum function-local
The 'Color' enum is only used for irreducible control flow detection. Johannes
already moved this enum in r270054 from ScopDetection.h to ScopDetection.cpp to
limit its scope to a single cpp file. We now move it into the only function
where this enum is needed to make clear that it is only needed locally in this
single function.

Thanks to Johannes for pointing out this cleanup opportunity.
