    llvm::ValueToValueMapTy& ValueMapping,
    llvm::DomTreeUpdater& DTU)

Description

Split edge between BB and PredBB and duplicate all non-Phi instructions from BB between its beginning and the StopAt instruction into the split block. Phi nodes are not duplicated, but their uses are handled correctly: we replace them with the uses of corresponding Phi inputs. ValueMapping is used to map the original instructions from BB to their newly-created copies. Returns the split block.
