Description

Delete all of the instructions in `DeadInsts`, and all other instructions that deleting these in turn causes to be trivially dead. The initial instructions in the provided vector must all have empty use lists and satisfy `isInstructionTriviallyDead`. `DeadInsts` will be used as scratch storage for this routine and will be empty afterward.

const llvm::TargetLibraryInfo* TLI = nullptr

llvm::MemorySSAUpdater* MSSAU = nullptr

std::function<void(Value*)> AboutToDeleteCallback = std::function<void (llvm::Value *)>()
