Nick Lewycky 72dba254ae Fix an oversight in isPotentiallyReachable where we wouldn't do any CFG-walking ... to find loops if the From and To instructions were in the same block. Refactor the code a little now that we need to fill to start the CFG-walking algorithm with more than one starting basic block sometimes. Special thanks to Andrew Trick for catching an error in my understanding of natural loops in code review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188236 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-13 00:03:47 +00:00
