  [LoopVectorize][NFC] Simplify ScaledReductionExitInstrs map (#123368)

For the following variable

DenseMap<const Instruction *, std::pair<PartialReductionChain,
unsigned>>
  ScaledReductionExitInstrs;

we never actually need the PartialReductionChain when using the map.
I've cleaned this up so that this now becomes

  DenseMap<const Instruction *, unsigned> ScaledReductionMap;
