Alexey Bataev c20e233020 [SLP] Replace TrackedToOrig DenseMap with parallel SmallVector in reduction ...

Replace the DenseMap<Value*, Value*> TrackedToOrig with a SmallVector<Value*>
indexed in parallel with Candidates. This avoids hash-table overhead for the
tracked-value-to-original-value mapping in horizontal reduction processing.

Fixes #189686
