	This is an optimization pass for GlobalISel generic memory operations.

Functions
bool	llvm::hasProfMD (const Instruction &I)
	Checks if an Instruction has MD_prof Metadata.
bool	llvm::isBranchWeightMD (const MDNode *ProfileData)
	Checks if an MDNode contains Branch Weight Metadata.
bool	llvm::hasBranchWeightMD (const Instruction &I)
	Checks if an instructions has Branch Weight Metadata.
bool	llvm::hasValidBranchWeightMD (const Instruction &I)
	Checks if an instructions has valid Branch Weight Metadata.
MDNode *	llvm::getBranchWeightMDNode (const Instruction &I)
	Get the branch weights metadata node.
MDNode *	llvm::getValidBranchWeightMDNode (const Instruction &I)
	Get the valid branch weights metadata node.
void	llvm::extractFromBranchWeightMD (const MDNode *ProfileData, SmallVectorImpl< uint32_t > &Weights)
	Faster version of extractBranchWeights() that skips checks and must only be called with "branch_weights" metadata nodes.
bool	llvm::extractBranchWeights (const MDNode *ProfileData, SmallVectorImpl< uint32_t > &Weights)
	Extract branch weights from MD_prof metadata.
bool	llvm::extractBranchWeights (const Instruction &I, SmallVectorImpl< uint32_t > &Weights)
	Extract branch weights attatched to an Instruction.
bool	llvm::extractBranchWeights (const Instruction &I, uint64_t &TrueVal, uint64_t &FalseVal)
	Extract branch weights from a conditional branch or select Instruction.
bool	llvm::extractProfTotalWeight (const MDNode *ProfileData, uint64_t &TotalWeights)
	Retrieve the total of all weights from MD_prof data.
bool	llvm::extractProfTotalWeight (const Instruction &I, uint64_t &TotalWeights)
	Retrieve the total of all weights from an instruction.
