Remove TwoAddressInstruction from the public headers and add an ID 

instead, since this pass doesn't expose any state to its users.

// This file implements the Two-Address instruction rewriter pass. In
// some architectures instructions have a combined source/destination
// operand. In those cases the instruction cannot have three operands
// as the destination is implicit (for example ADD %EAX, %EBX on the
// IA-32). After code generation this restrictions are not handled and
// instructions may have three operands. This pass remedies this and
// reduces all two-address instructions to two operands.
