Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.

insertion of MachineInstr instances from anywhere in each

MachineInstrs into or out of MachineBasicBlocks.

LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

A = B op C where A == C, but this cannot really occur in practice
because of SSA form. Add an assert to check that just to be safe.

more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.
