Xin Tong fcc344502c [JumpThread] We want to fold (not thread) when all predecessor go to single BB's successor. ...

Summary:
In case all predecessor go to a single successor of current BB. We want to fold (not thread).

I failed to update the phi nodes properly in the last patch https://reviews.llvm.org/rL300657.

Phi nodes values are per predecessor in LLVM.
