[PATCH] D29381: [PM/LCG] Remove the lazy RefSCC formation from the LazyCallGraph during iteration.

[Chandler Carruth via Phabricator via llvm-commits]

Another update to actually remove all the support variables for maintaining an
in-flight DFS walk from the class. Somehow forgot to remove these, they're all
dead now.

In entertaining news, if you look carefully you'll spot places where this patch
actually fixes bugs due to failing to correctly manage all these variables. Yay
for a simpler approach!
