This affects the comparison instructions which now read "icmp ult a, b". This mimics LLVM's style and makes it simpler to add instruction flags in the future, such as "load v1" -> "load aligned v1". These enumerated operands and flags feel like opcode modifiers rather than value operands, so displaying them differently makes sense. Value and numeric operands are still comma separated.
