Thanks for both answers. I created one meanwhile, that recognizes
dependencies between two instructions based on MachineInstr::getOperand,
TargetInstrDesc::getImplicitUses and TargetInstrDesc::getImplicitDefs.
It works pretty fine. I will contribute it back as soon as I can (at
first, I have to ask my bachelor's thesis leader).
