Ted Kremenek 93668002c4 Restructure CFG builder to have just one visitor path instead of two. The result 
is an algorithm that is much easier to understand and slightly more efficient.
Thanks to Mike Stump for our discussions on the CFGBuilder and his comments that
helped prompt this long needed cleanup.
