FindPredecessorBlocks - Put the predecessors of Info->BB into the Preds vector, set Info->NumPreds, and allocate space in Info->Preds.

Definition at line 242 of file SSAUpdater.cpp.

References llvm::BasicBlock::begin(), llvm::pred_begin(), llvm::pred_end(), and llvm::SmallVectorTemplateBase< T, isPodLike >::push_back().
