da38dc5180 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.

4a2e2b54f6 This pass should not require phi elimination or live variable 
analysis. It should only preserve them and update LiveVariables if it
already ran.

b755d35fd2 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

ef7c077e63 Make LiveVariables::HandlePhysRegUse and 
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.

496be157cc 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.

9181e0ab5b Remove TwoAddressInstruction from the public headers and add an ID 
instead, since this pass doesn't expose any state to its users.

90aeecae42 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.
