Rename TarjanSCCIterator -> scc_iterator

* Increases consistency with other iterators (e.g. df_iterator, po_iterator...)
  * It's shorter
  * We don't name classes by the implementation, we name it for the interface!

// This file provides passes to print out SCCs in a CFG or a CallGraph.
// Normally, you would not use these passes; instead, you would use the
// TarjanSCCIterator directly to enumerate SCCs and process them in some way.
// These passes serve three purposes:
// (1) As a reference for how to use the TarjanSCCIterator.
// scc_iterator directly to enumerate SCCs and process them in some way. These

//
// (1) As a reference for how to use the scc_iterator.
// (2) To print out the SCCs for a CFG or a CallGraph:
// analyze -cfgscc to print the SCCs in each CFG of a module.
// analyze -cfgscc -stats to print the #SCCs and the maximum SCC size.
