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.

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

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.
