  [LoopFusion][NFC] Share fusion tail between guarded and unguarded paths (#205492)

`performFusion()` and `fuseGuardedLoops()` carried two
character-for-character identical tails: header-PHI migration plus latch
rewiring, and the SCEV-forget / block-merge / latch-merge finalization.
Extract them into `rewireFusedHeaderPHIsAndLatches()` and
`finalizeFusedLoop()` and call both from each path.
