Functions
InstructionCost	llvm::slpvectorizer::getShuffleCost (const TargetTransformInfo &TTI, TargetTransformInfo::ShuffleKind Kind, VectorType *Tp, ArrayRef< int > Mask={}, TargetTransformInfo::TargetCostKind CostKind=TargetTransformInfo::TCK_RecipThroughput, int Index=0, VectorType *SubTp=nullptr, ArrayRef< const Value * > Args={})
	Returns the cost of the shuffle instructions with the given Kind, vector type Tp and optional Mask.
std::pair< InstructionCost, InstructionCost >	llvm::slpvectorizer::getGEPCosts (const TargetTransformInfo &TTI, ArrayRef< Value * > Ptrs, Value *BasePtr, unsigned Opcode, TargetTransformInfo::TargetCostKind CostKind, Type *ScalarTy, VectorType *VecTy)
	Calculate the scalar and the vector costs from vectorizing set of GEPs.
InstructionCost	llvm::slpvectorizer::getBlendedLoadCost (const TargetTransformInfo &TTI, Type *VecTy, Align Alignment, unsigned AddressSpace, TargetTransformInfo::TargetCostKind CostKind)
	Returns the cost of a BlendedLoadVectorize node loading VecTy: two masked loads (one per candidate base), a xor to negate the false-lane mask and a select.
