  -----------
  [VectorCombine] Pull out TargetCostKind argument to allow globally set cost kind value (#118652)

Don't use TCK_RecipThroughput independently in every VectorCombine fold.

Some prep work to allow a potential future patch to use VectorCombine to optimise for code size for -Os/Oz builds (setting TCK_CodeSize instead of TCK_RecipThroughput).

There's still more cleanup to do as a lot of get*Cost calls are relying on the default TargetCostKind value (usually TCK_RecipThroughput but not always).
