Chandler Carruth 8d91579fa9 [LCG] Add some accessor methods to the SCC to allow iterating over the
parents of an SCC, and add a lookup method for finding the SCC for
a given function. These aren't used yet, but will be used shortly in
some unit tests I'm adding and are really part of the broader intended
interface for the analysis.
