I think these are the features I would class as tuning:

  FeatureExperimentalZeroingPseudos
  FeatureZCRegMove
  FeatureZCZeroingGP
  FeatureNoZCZeroingFP
  FeatureZCZeroing
  FeatureZCZeroingFPWorkaround
  FeatureStrictAlign
  FeatureBalanceFPOps
  FeaturePredictableSelectIsExpensive
  FeatureCustomCheapAsMoveHandling
  FeatureExynosCheapAsMoveHandling
  FeaturePostRAScheduler
  FeatureSlowMisaligned128Store
  FeatureSlowPaired128
  FeatureSlowSTRQro
  FeatureAlternateSExtLoadCVTF32Pattern
  FeatureArithmeticBccFusion
  FeatureArithmeticCbzFusion
  FeatureCmpBccFusion
  FeatureFuseAddress
  FeatureFuseAES
  FeatureFuseArithmeticLogic
  FeatureFuseCCSelect
  FeatureFuseCryptoEOR
  FeatureFuseLiterals
  FeatureDisableLatencySchedHeuristic
  FeatureForce32BitJumpTables
  FeatureUseRSqrt
  FeatureLSLFast
  FeatureAggressiveFMA

The `ProcA55` type features set `ARMProcFamily`, which seems to be used for tuning everywhere they are used, so would probably class as tuning features too.
