New Revision: 155881

URL: http://llvm.org/viewvc/llvm-project?rev=155881&view=rev
Log:
Fix bug in HackedSCCFinder where it unconditionally set reachable flag.

Shouldn't have any functionality changes in terms of analysis results,
  but did result in unnecessary cloning of misc nodes that happened
  to be the leader of an SCC that didn't need to be cloned.
