  Log Message:
  -----------
  [SLP] Cost struct-returning intrinsic calls with a vector library mapping

getVectorCallCosts queried the vector intrinsic cost with a type-based-only
IntrinsicCostAttributes. That path always scalarizes struct-returning
intrinsics (e.g. llvm.sincos), which have no VFDatabase name mapping.
Retry with an argument-aware query when the type-based cost looks scalarized.

Fixes #200644
