This pass should not require phi elimination or live variable

analysis. It should only preserve them and update LiveVariables if it
already ran.

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.

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.

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.
