In some cases natural use of abstraction in avo programs can lead to redundant move instructions, specifically self-moves such as MOVQ AX, AX. This does not produce incorrect code but it is incorrect and inelegant. This diff introduces a PruneSelfMoves pass that removes such unnecessary instructions. Closes #76
