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.

Currently we cannot handle two-address instructions of the form:
...
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.

Add TwoAddressInstructionPass to handle instructions that have two or
...
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.
